Golf IV / Jetta IV :: 2001 - Getting CEL Again After 1 Year Replacement Of Catalytic Converter
Car is a 2001 MK4 Jetta with 2.0 Auto Tranny and 120k miles, stock exhaust
A little over a year ago I was getting a cel and the code that was being thrown was a DTC 16804. I changed the cat and both o2 sensors and the light went away for almost a year. The other day I was driving and the light came on again. Scanned the car and its the same 16804 code. I replaced the front o2 sensor thinking it was bank 1 but it didn't solve the problem. I clear the code and it comes back the next day. I'm finding it hard to believe that the cat is bad after only a year. I checked for vacuum leaks, faulty MAF and nothing under the hood looks out of whack. My mission is up next month and the car won't pass with this code.
Prius (2001-03) :: Loud Noise Coming From Exhaust System / Catalytic Converter Replacement
After hearing some loud noise coming from my exhaust system, it was determined that there is a hole (from rust) in part of the cat. assembly. Three shops advised for replacement, there are no aftermarket products for this unit. I have NOT gotten any error codes, the only problem is the noise. What to do? The car is 10 years old with 86000 miles. I have been reading about some of you getting just the one piece and having it welded on, but I do not believe any of the shops here will do that, and indicated that it would be a very temporary fix.

I have a 2001 VT GTI with 155K miles on it. It is in very good condition. I have loved the car except for the high maintenance costs that typically seem to be associated with VWs.
I found out this week after my check engine light came on that the car needs a new catalytic converter and a new new secondary air pump.
Let's assume that this diagnosis is correct and the repair is accurate for the sake of this posting (and I have no doubt it is). In other words, I don't want to get my question derailed on that issue.
The car has new Michelin tires on it and runs well. The problem is that it will fail the state emissions test I am required to take next December, and I will either be forced to have the car repaired or will not be able to get updated license tabs (isn't that sweet?!).
It seems that I have a few options:
1. Get the repair done (ouch) and keep driving the car for a few more years. Repair cost is about what the market value of the car is (from what I have seen).
2. Sell the car "as-is" between now and December and see what cash I can get out of it. Any buyer will discount the value of the vehicle based on the repairs needed. Of course, then I'll need a replacement vehicle of some sort.

View 5 RepliesSonata NF (2006-10) :: Catalytic Converter Clicking / Ticking / Rattling?
I have noticed lately, when the car is hot, while pulling into my quiet garage, and even when the car is in park, engine running --- hearing some clicking / ticking coming from, or near the Catalytic Converter.... It sounds as if a small piece of metal is rattling inside with the flow of air... It stops clicking once the engine is turned off.

I have a 2001 Ford F250 Diesel. I recently cut the 4 inch exhaust pipe right behind the end of the cab cutting off the muffler and I thought the catalytic converter as well. I was talking to another super duty owner and he said he thought there was another catalytic converter further up in the pipe. Is this true? If so, how far would would I have to cut it to cut it off. Would this make the truck any louder...wouldn't mind if it did.

Toyota says the code is P0420 and the Catalytic Converter is rattling under heavy acceleration showing the Catalytic converter is bad and should be replaced. Toyota wants 2,334.00 which seems very high to me. Is it the Catalytic converter? The car is a 2004 Toyota Prius.

Got a rattle from the car, I think it's the catalytic converter heat shield. Looking for any pictures of what it looks like? I don't know if it is a full cover on our Toyota's, or a half cover. I will post a picture of what mine looks like now that it is rattling later today. Hoping it's an easy fix.

Suzuki - Xl7 :: Exhaust Heat Shield On Catalytic Converter Fell Off
My wife drives a 2001 Suzuki XL7. While she was out, the exhaust heat shield fell off the catalytic converter. My question is does this affect the car's ability to function in any way? Is it still safe to drive? My wife is freaking out over it.

I own a 2000 E 250 Econoline van with 170,000 miles. I've been encountering loss of power on acceleration for months. Terrible gas mileage (8-10 mpg) and just recently, I get that rotten egg smell when I gun it and and travel above 65/70. I can feel heat from under the van when i step out as well. I've been blowing individual coil packs every other month after a long drive with a lot of inclines. It all points to a clogged catalytic converter. This van has 3. A front left and right by the manifolds, and a large one before the muffler. My question is, what causes them to go bad? I want to fix the cause before spend the money on new cats. Ive heard a rich fuel mixture could do it. Are there sensors that need to be changed?

What would cause both Cat converters to fail at 20,000 mi.? Mine went out and the back pressure caused the engine to knock under acceleration. Also blew out an injector and plug. Luckily it was under warranty but wonder what could caused it.
View 8 RepliesToyota - Repair - Corolla :: Loudest Rumbling Exhaust Sound / Catalytic Converter Replacement?
Yesterday my 1995 Toyota Corolla (which runs well otherwise) started making the loudest rumbling exhaust sound I've ever heard whenever I stepped on the gas pedal. It also felt like it had trouble accelerating when I would try to get going after a stop. I took it to a mechanic right away, who says it needs a new catalytic converter and resonator pipe.
My boyfriend says this is a repair he could do. He has done some car repair and worked with a mechanic before, so I am considering trusting him on that, but I don't know what types of repairs he's done before and I know he has never worked on this model. What would you take into consideration whether or not it would be safe to attempt this repair at home?
Ford F-150 (2004-2008) :: 2005 - Catalytic Converter Rattling On Driver Side And Check Engine Light Is On

View 10 RepliesJetta :: Change Catalytic Converter After 12,000 Miles?
My car had its check engine light come on a few days ago, and the engine started to get extremely loud whenever I was accelerating. I would also smell gas whenever I would start the car. I decided to take it to a mechanic, who did a diagnostic check and told me that my catalytic converter was busted. This troubled me because I had just had the part replaced a little over two years ago. I figured the part would still be under warranty, but the mechanic that I had used to replace the cat told me that it was only under warranty for one year or 12,000 miles, according to the distributor. Well, I got a hold of the distributor, and he told me that he didn't have the information for the specific part that he used (he just told me that he "figured" it would be one year or 12,000 miles because most of the parts that they receive have warranties of that length....). Shops are closed now for the weekend, and I am getting worried about my bank account here...should I be?
Well, my questions for you all are as follows:1) Have you all ever heard of a catalytic converter ever having only a 1 year or 12,000-mile warranty? My current mechanic tells me he has never heard of one being so short, and that usually they are 5 years or 50,000 miles. I did minimal research on the internet and also found similar results.2) Who do I need to get into contact with in order to find out how long the warranty is, and how I redeem the warranty?
Subaru - Forester :: 2001 - Smoking From Catalytic Converter Area
I'm getting smoke from the catalytic converter area on my 2001 Subaru Forester. The smoke smells of rubber or oil. I've only noticed it after the car has been driven up a long, steep incline of at least a couple of miles. I've never seen it happen after normal highway driving. The car runs fine, gas mileage is good, CE light is not on, 85K miles, regularly serviced.
View 2 RepliesNissan - Sentra :: 2001 - Burning Plastic Smell From Catalytic Converter
Where do I start. I have a 2001 Nissan Sentra. 128,000 miles. In Aug. of last year, the engine detonated, so I had it replaced along with other parts. Shortly after that, I noticed a burning plastic smell coming from the car after driving it for a while. I confirmed that that the smell wasn't coming from a plastic bag. Fast forward to Dec 2011, my check engine light comes on. I go to Autozone, have the code read; it's the dreaded 420 code. I go to have it checked out, was told my cat went bad and probably because of the old engine and that the smell is probably coming from that.
The check engine light went off on Christmas day. Fast forward to last month, the light comes on again and I pony up the cash to have the cat replaced since inspection is coming up in June. Now, I had an engine diagnostic run right before I got the cat replaced and it came up fine. The cat was replaced on 4/20. Everything seemed fine. The burning plastic smell went a way, but lo and behold, it came back this week. I don't know what to do. I did a little search on the net and it seems that burning plastic smell indicates there is something going on with engine and possible misfire.
Golf IV R32 :: How To Make Catalytic Converter Ready
Took my car in for emissions and says catalytic converter is not ready.
What can I do to make this go to "ready"?
I've recently got my computer flashed with new programming.
Since it's been flashed, I've driven the car over 400 miles.
All of the cars self checks should be complete, I can't figure out why the catalytic converter won't go to ready!
Any thoughts or tricks to make it work?
Golf IV R32 :: Catalytic Converter - Heat Shield Rattle
The catalytic converter shield is tack welded on the front end but free on the rear end. There was originally some braided wire packing at the rear to keep the shield from rattling against the pipes. Mine was deteriorated and had been damaged, I think, when I sustained some oil pan damage last summer -- big jolt to the system when running over a muffler on the highway.
The fix is simple. Bought a foot of 3/16" braided stainless steel cable. I used about 8 inches and layed in the lower bead line on the catalytic converter shield (see picture below). You can see a bit of the cable thru the gap in the upper/lower shield on the left side. (1/4" cable would be a better fit, but this will work for a long time.) Cost: $1.84
The local VW parts man dug out an exploded drawing of the system but it showed NO parts or packing for this problem.
