Remove the front o2 and drive it, if veichle come alive and has a lot more power than you can suspect the cat. be very careful not to damage the 02, some do not want to come out, could damage threads, if you cannot remove it unbolt the cat from manifold and drive.

More then one person on this site have suggested that that the catalytic converter can come apart and clog itself or the muffler, thus causing a serious lack of power and fuel mileage issues. If true it would seem that this may be your problem as well.

appreciate your keeping everyone updated on what exactly is found to be wrong with the car. All to often someone will pop on here with an issue but we never hear back as to exactly what if anything was ever corrected.

VERY good point. As I am reading this I feel badely for you because your car DOES have more wrong with it then the CAT going bad. Your Cat went bad becasue this car has a known coolant leak problem. Your coolant is leaking into the exhaust and it has broke down your CAT and colgged it up. I can say this with much certainty because there is a lawsuit against Chevy right now for this problem. My 2002 Impala never showed coolant on the garage floor but when They tried to suction the coolant out at the shop to replace it they could tell it was leaking. Sure enough if you do a web search about this car and a coolant leak problem you will get tons of info. Chevy recalled the 3.8 liter for this problem but not the 3.4 because they would have lost a fortune. There for, like me, you may not notice a coolant leak but it has leaked into your exhaust. You will need to have it suctioned to check but I will be willing to bet you have a cooant problem.

I don't know what it is with GM and Ford with their inferior gaskets. I know the "other" cars use real gaskets and they don't have the problem. C'mon GM.....C'mon Ford, spend a few extra dollars and get it right.

I agree. I'd even pay the few extra dollars it cost to have better gaskets.

Do you know how much more it would cost to prevent these kinds of things? First you would have to do a ton testing to find all the problems that could possibly crop up in any given automobile. Next you would not be able to go with the low bidder anymore due to lesser quallity control standards. All these things would add greatly to the overall cost of the automobile. A cost that I'm sure you would not want to stomach.

About 1 year ago the CAT went bad on my 2001 LS, 3.8L and Chevy replaced it... Many here will remember my story... Since then the car has run like a rocket. It never threw any codes either. Also, I have no coolant problems, no coolant lose as far as I can detect. I replaced the T'Stat about 5 months ago and the coolant was perfectly clean looking with no obvious gunk around the old thermostat or under the radiator cap. Also, my oil looks fine each time I change it.

There is no doubt the CAT can go without a coolant problem. Not sure if your car was one that was recalled for it (not all were) but MANY have it and my CAT in ruined due to the coolnat leak. Congrates on not haveing a coolant problem. Mine has been a pain in the you know what!!
