No replacement Catalytic Converter for Geo Prism

Showing 4 out of 4 Posts
Question From Guest on No replacement Catalytic Converter for Geo Prism

My '97 Geo Prism is ready to be junked because my mechanic says that "they don't make catalytic converter for your car, anymore." With a spent C.C., I can't pass the smog test and renew the Prism's registration. Anyone out there know how to solve my problem? Thanks.

Response From Loren Champlain Sr

Just to add; You'll need to find out why the cat is bad. A cat will destroy itself if you have an engine management problem. This needs to be addressed before you replace the cat so that you don't ruin the new one.
From the two pics that Tom showed you, the top one must be either welded or clamped in place. The bottom one is a 'direct fit' type. I'd recommend going with the direct fit. If you have had the trouble codes pulled, post them here, and we'll try to guide you through any problems.

Response From Tom Greenleaf Top Rated Answer

So true and thanks Loren. I don't know why but when I saw the type I was thinking it was rusted out at the connections more than burned out which absolutely requires finding out why!

Response From Tom Greenleaf

If just the converter itself it's available quickly as seen below at AutoZone by chance I checked them - check anywhere you wish.

Original ones are suggested and cost more and can be worth the extra and should still be available?

Muffer type shops should be able to do this with generic parts too if you are wise to that (I don't care for that way) quite a bit.

1991 Geo Prizm stutters during acceleration

Showing 6 out of 6 Posts
Question From deuce22deuce on 1991 Geo Prizm stutters during acceleration

Hello. I'm having problems with my 91 Geo Prizm 1.6L, 90,000 miles. I recently had the timing belt, catalytic converter and the pipe that goes from the catalytic converter to the engine replaced. About a month after I had the work done, my car started stuttering during acceleration. It doesn't stutter within the first few minutes of driving, but it does after that and seems to get worse the longer I drive. The car hasn't stalled out because of this problem, but sometimes feels like it might. And it seems to run fine before and after the stutter. Any help I can get would be greatly appreciated, thanks!

Response From deuce22deuce

Nevermind, I'll just take it to a professional and post what was wrong in here. lol One post all day.

Response From way2old

Sorry for the delay. We also have full time jobs (usually more hours working than off)and families to be with. How long since the vehicle has been tuned up? Fuel and air filters changed? Look at the common things first. Let us know and we will try to help. We might not be as fast as you want us to be, but we truly do care.

Response From deuce22deuce

Look man. I wasn't trying to be mean. I just thought there would be more people on here. I didn't realize it was such a small community. But thanks for the advice. I'll just take it to the mechanic and have it looked at by an expert. It's pretty hard to get advice on a forum considering how little I know about cars. I apoligize if you think I somehow insulted you. Have a nice life!

Response From way2old

Wasn't insulted. Just explaining why there was not a faster response.

Response From Tom Greenleaf Top Rated Answer

Deuce22Deuce : You were seen and I put your post on watch quickly when you first posted. Just know that I didn't think I had anything earth shattering to suggest so I let it sit and wait for perhaps another to come by. There are several of regulars here and the whole world can watch and suggest away at will.

This forum is active and tended to as best we can. It would hurt if a regular makes a post basically saying "I don't know" or something as other regulars might see that it's already attended to and not persue it or even look in.

As a regular I try to see what topics haven't been responded to first and check the ones with responses last. Know that it's a lot just to read all the "unread" posts that come thru this site and even when we have the time which varies by our own real world schedules we can get caught up deep in one situation taking up lots of time.

Hey - there's only so much a forum for car issues can do and only so many eyes to watch. At this post 32 folks have already seen your first post so it didn't get ignored.......

P0420 Geo and Mazda

Showing 2 out of 2 Posts
Question From comnavguy on P0420 Geo and Mazda

Both of these cars, each in excess of 130,000 miles, is showing code 0420 "catalyst efficiency below threshold Bank 1"

Is that the catalytic converter? The question comes from one lady just replaced the converter a year ago.

Neither vehicle shows any codes for the 02 sensors.

Response From Hammer Time Top Rated Answer

95% of the time, that is a bad Converter. If she just had hers replaced, then it is under warranty. They carry a mandatory 5yr/50K

How to check catalytic converters.

Showing 2 out of 7 Posts | Show 5 Hidden Posts
Question From Mr.scotty on How to check catalytic converters.

I believe you can check by measuring the temperature from the beginning of the cat, the cat itself, and behind the cat and there should be a 100-200 degree difference rite?

You can also do a pressure test before and after the cat rite or wrong? Ifso what should the two common pressure specs be?

I never had to test a cat before So i just want to see If I'm rite or if theres a easier way to do it?

Thanks

Response From Hammer Time

Sure you can if you are testing for a plugged converter but he was not. He had an EFFICIENCY code.

Response From Mr.scotty

Oh..ok.
What tests would you do for an efficiency problem?

Thanks for replying!

PS: I didn't mean to hijack anyones threads I just get cought up in the moment I guess.lol
I'll keep my own questions for my own threads for now on, I promise.

-Scotty

Response From Hammer Time

There is no test for that. the computer already performs about the most accurate test possible because it takes many factors into consideration before determining that.

When someone asks a question here on the forum about their car, they don't appreciate someone else coming in and asking their own questions and sending the thread in a totally different direction, taking the attention off their problem and turning it into someone else's private tutoring session..

Response From Mr.scotty Top Rated Answer

So what would be the nxt step, to replace the cat?
When a geo metro I was working on had a cat efficiency code after replacing the upstream o2 sensor for a heater circuit problem and, then having the ECU reprogramed by the dealer the cat efficiency code never came up again, Would the o2 sensor have fixed this or the new software update?

I understand fully about stealing the attention away from them, Thank you for being nice about it and I promise it will not happen again.

Response From Hammer Time

That's a pretty rare situation and I suspect that the reprogramming by the dealer changed the parameter for setting the code and made it less sensitive.

Response From Mr.scotty

I reason I had it reprogramed cause It was not completing the drive cycle even after 500 miles.
Soon as it was reprogramed it completed it in like 70 miles, I guess It's a good thing to get older vehicles updated to the new software anyway and it was only like $100 bucks for this car.

How often do you think a car should be updated?
