How do I chg my catalytic converter on my 88 chevy pu?

My truck smells a little, and I think the catalytic converter is going or has gone out. Can I change it on my own?



If anyone can leave me some detailed instructions on how I can do this, it would be much appreciated.



If no one can leave me detailed instructions to do it, because it is something that must be mechanic shop serviced, please let me know.



It would mean alot to me and 10 points to the considerate one to leave me correct instructions.



I appreciate detailed instructions, as I always strive to leave detailed instructions in my answers to peoples request for instructions on yahoo.



Thank you so much.How do I chg my catalytic converter on my 88 chevy pu?when a convertor goes bad it is usaully just because it is clogged up. it is good to replace it but you can take it off clean it and put it back on. your dont have to weld it but a lot of people do. you can use exauhst clamps if the ends are tappered enough. but welding is the most durable way to hold it back up. being that the metal is so thin your gonna want some one with a lot of welding experience to do it for youHow do I chg my catalytic converter on my 88 chevy pu?unless you have a welder or can weld i dont think you can do it you have to cut it off then weld it on

My car didnt pass the inspection, it overall passed everything except the NOx(ppm)...?

I changed the catalytic converter, exhausts, and i think it could be a sensor or something. Its for a 95 camaro v6 3.4L. How can i find out where the source of it is coming from to make the engine light stop going on? If its a sensor, how can i find where its located and how much do they sell them for at the parts store? Thanks.My car didnt pass the inspection, it overall passed everything except the NOx(ppm)...?You need to go and speak to the chap who did your test. He is the automotive engineer. Hell will, I'm sure, be more than happy to put you in the right direction.



It is hard to say from your description. The problem could be anywhere, really. I suspect one, or even two oxygen sensors that tell the ECU when to meter the fuel and how much. Also the' mass airflow' sensor could be dirty, and thus giving a more than correct reading to the computer.



I would also run the vehicle on a tank full of premium gas, and add a can of B12 to the tank, too. This will clean the injectors, and get rid of any deposits in the cylinder head.



Before you do anything, you might take off the EGR valve and clean off any carbon deposits. The tube that feeds the EGR valve from the exhaust will need to be cleaned out thoroughly, too. I would do this first, before paying out any cash for sensors.

Best of luck

Dr AntonyMy car didnt pass the inspection, it overall passed everything except the NOx(ppm)...?you need a pro to get after it/you are throwing parts at it and it aint fixed yet//thats an expensive way to do itMy car didnt pass the inspection, it overall passed everything except the NOx(ppm)...?go to autozone and have therm hook it up to their diagnistic testor to see what the code is. im guessing its the o2 sensor it is located in your exhaust coming off the manifolds. it takes a special socket to remove it cost is about 10 dollars for the socket the price ot the new o2 sensor is 50 to 75 bucks. also i would change my spark plugs b4 having it rechecked good luckMy car didnt pass the inspection, it overall passed everything except the NOx(ppm)...?you could cheat rather than fix it. run your car till the tank is almost empty. put in 10 gallons of premium gas (no ethanol) and two bottles of rubbing alcohol bounce the trunk enough to mix. drive enough to clear fuel line of unmixed gas and go have it tested right then. it should pass. (mixture will burn hotter and cleaner though not real good for engine it won't hurt it. )

How can I reset the Check Engine light on a BMW E30 1988 325?

A year ago, I changed the catalytic converter after a smog test failure. After, it passed with flying colors. Check engine light flashes in a sequence of %26quot;flash, flash, on%26quot; after using the ignition key method (this means it needs an oxygen sensor). I replaced the oxygen sensor; however, the check engine light continues to give the %26quot;replace oxygen sensor code.%26quot; Is there a way to reset the CE light without going to the dealer? I hear that if I disconnect the terminals of the battery for a lapse, it will re-learn its sensor values, and reset, is this true?How can I reset the Check Engine light on a BMW E30 1988 325?Get a code reader and reset tool from Peake Research. They sell them direct, or check online for other BMW specialist resellers who often offer them at a discount. It'll provide easier to read code reading than the %26quot;stomp test%26quot; method, and you can reset the lights, too.

My Chevy Truck Failed the Emission Test HELP?

Hi guys I just joined this forum and this is my first post and I really need some HELP.

I have a problem and would like come suggestion on how to fix it.

I have a 1988 Chevy truck with a 4.3 motor and I swaped it out for another 4.3 motor because the other one was no good . I had to take it for a emission test but before I did I changed the oil 'oil filter replaced the plugs' rotor and cap and then took it for the test and it failed.

Here's the reading of the test.



ASM 2525 Curb Idle

Limit Reading Result Limit Reading Result

HC ppm 83 190 FAIL 200 419 FAIL

IT FAILED : So I brought it back home and I took of the EGR valve and checked the ports to make sure they where not cloged and they where clean and I cleaned the EGR valve put it back on. I checked the vacuum line on the EGR valve to make sure it was opening right after idle and checked all other vacuum lines for leaks.I dumped some good throttle body ' valve and combustion chanber cleaner down it and let it site . Then I started it and boy did it ever smoke. I changed the plug wires air filter and pcv valve and took it for another test.

Can anyone give me a suggestion on what to do next.

I checked the timing but I wasn't sure what the timing is suppose to be. I looked in my book but it did not say and I looked on my truck but nothing.

Anyhow I read in the book that the ignition timing cannot be abjusted on 1996 and later SFI engines on a 4.3L v6 engines because it is electronic controled. So what can I do to bring the HC and CO down to make it pass.

Thanks in advance for any HELP.

PS: and I changed the catalytic converter 2 years ago ' I put a universal cat on it and now someone told me that they only last one to two years ' Is that true.My Chevy Truck Failed the Emission Test HELP?LOL, (not at you),

everybody always says replace yhe O2 sensor,

well in this case they would be correct,

if you had a scan tool available you would note the high block learn and integrator numbers,

simply replace the O2 sensor and go pass your test

your welcome in advance,



if you do as I say you will pass!!!!!



change only the O2 sensor, not the cat.,

the egr valve only works to reduce NOX emissions by lowering combustion temperature, the cat helps burn excess hydrocarbon but only to an extent, a good running fuel injected vehicle could pass a HC and CO emission test without a cat, however it would fail in the nitrogen oxide area!!My Chevy Truck Failed the Emission Test HELP?If both HC and CO are high, the vehicle may have a bad catalytic converter or an air pump problem. if you put a new catalytic converter on it prior to swapping motors, the old one probably plugged it up.



Also, you need to make sure that the truck is good and hot prior to the test. The cat is only effective when it's hot.My Chevy Truck Failed the Emission Test HELP?Is running rich, check for loose and/or dirty connectors and like mentioned, the O2 sensor can be reading wrong. By the way... is all stock? Did you changed anything like High Performance? Such as, Exhaust Headers, Performance Chip or any other toy that can throw off the sensor readings?My Chevy Truck Failed the Emission Test HELP?my trust in bustas here he has bailed me out beforeMy Chevy Truck Failed the Emission Test HELP?Did you say the timing hasn't been set?

On these it must be set.

There is a wire you disconnect, then a timing light will work.

I am not sure where it is, but I would get the timing set first.

This will cause your emission problems.

How much should I drive a 2003 Toyota Corolla to get the readiness code active again?

I had a check engine light (code p420) and my mechanic said it will cost $1200 to change the catalytic converter but usually this is casued by a defective oxygen sensor.



I learned through some research that if I disconnect the battery and connect it back, the check engine light disappears (it did). When I took the car for emissions testing diagnosis I learned that my car was not ready to throw out a report as it was not driven long enough after the battery disconnection and it should be, before the %26quot;readiness code%26quot; is reset.



My question: How much should I drive before the emissions can read from my car computer? There is no check engine light right now but if I drive too long, it might come back, so what is the range of miles/speeds that I should drive?



Readers who have especially had experience with a Toyota Corolla can add more value to this question.



Thanks guys!How much should I drive a 2003 Toyota Corolla to get the readiness code active again?Best if let car sit overnight,cold engine,with half full gas tank,start and let it warm up like 10 minutes,with AC on,then drive nice and easy local and highway speed,best when there is no or very light traffic.Whenever have to stop,leave engine idling until finish,all monitor should run within half an hour,anything no good will show up by the check engine light,or all system ready or completed.How much should I drive a 2003 Toyota Corolla to get the readiness code active again?I think you drive it for 40-50 miles before it can reset itself.How much should I drive a 2003 Toyota Corolla to get the readiness code active again?drive at speed 80 to 90 km /h for 45km

Question for car modifiers?????

How come when people change their exhaust system to a performance one, they always go for a cat-back or a cat-back with extractors and not a full whole exhaust system including all the pipes. I see a lot of people that do not change their catalytic converter to a better performance enhancing one. Is it because they are too poor or not as good?????. I want to know.Question for car modifiers?????Usually doing the cat back system as well as the headers will give you power gains decent enough to do them. A lot of modifiers leave the catalytic converters because for one, it's an added expense with very little effect. Secondly, smog. People don't want to go through replacing the converters and fail the smog and then putting the old one back. Just a pain in the behind. Personally, I'd just leave the catalytic converters alone. Headers and the cat back system will do a good job in the power gains department. It's just the beginning of the fun world of modification.Question for car modifiers?????punch holes in your cat



sounds great



illegal



but greatQuestion for car modifiers?????cat back is easier, also a lot of OBD II (newer) cars require that both the pre cat o2 sensor and post -cat 02 sensor remain intact for emissions purposes. I would personally go with headers and full exhaust because usually next to the mufflers, stock headers are the most restrictive.

Catalytic converter warranty for a 2006 330i BMW?

Hello,



I have a 2006 330i BMW that has 72000 miles, the 'check engine soon' light came on, after taking for a diagnostic the computer says that the catalytic converter may need to be changed.

I understand that the EPA enforces a warranty on catalytic converters, how can I look for this regulation for this vehicle and how do I make BMW to comply with it?



Thanks,

Agustin.Catalytic converter warranty for a 2006 330i BMW?Whoever diagnosticed it is a retard. Bmw's dont bring up CHANGE CAT CODES. Take it straight to the dealership and have them diagnose it. It is probally a bad 02 sensor or something.Catalytic converter warranty for a 2006 330i BMW?The EPA requires auto manufacturers to cover all emissions related components (your catalytic converter qualifies as that) to be covered by a 10 year/ 100,000 mile warranty. If your catalytic converter is bad, then it will be covered under warranty.Catalytic converter warranty for a 2006 330i BMW?Chances are that the good people at BMW will not hastle you about this. But, you should clean out your IDLE AIR CONTROL VALVE and throttle body with Gum-out first, as these things actually can CAUSE a problem with a catalytic converter. Also, where you buy gas can affect this. READ your manual about emissions warranties. Hopefully, you are in compliance with the BMW maintenance schedule!!!
