i have a 2001 automactic i have like no power the engine seems ok the cat not plugged i am thinking transmission maybe slipping or somthing but i would think it would throw a code could you have a noticable problem and not throw any codes?

 

 

ok its the ls ver. smaller motor 4 speed automactic car runs fine it idles around 500 in gear when leaving from a stop i seems to surge and feels like like its driving in slow motion if you stand on it it bogs for a second i cant get the front tires to spin at all at 55 it kinda pullsates 108000 m iles can it show this type of behavior with out tripping a code you can tell it has a problem some where i going to the dealersship to see if i can have mech test drive it ill let ya know what he or she says

 

The cat's not plugged? Sounds like the prob. I had but I was also throwing a check engine code. The model and VIN I had Chevy replaced it for free because there's an extended (80K to 120K) mile warranty on the cat for the 01 SS. They tried to make me pay it but after they received a call from GM HQ in the morning, they happily gave it to me for free.......

Mine was also replaced free.

 

I have a 2005 Monte Carlo and it threw the code 0420. Many have told me that the code means that I need a new cat. Is that the case? Are there any special policies or warranties that may cover my vehicle? Is it possible that its not my cat? Any information would be greatly appreciated.

Thanks,

 

How many miles on the '05? http://consumerguideauto.howstuffwor...te-carlo-5.htmThe Exhaust Emission Warranty covers corrosion-related parts for 2 years/24,000 miles, plus 8 years/80,000 miles on the catalytic converter and any on-board diagnostic device.

 

Unfortunately, I am outside of both warranties. I have about 98k on it and was aware of the warranties you mentioned. I did however run across a response about a specialy policy that I wasnt aware of, so I wanted to check and see what additional info I could get and to also see what others were told and view their trials and errors.

 

I know there was a special policy on some '01s and'02s but I have heard nothing about an extension on the '05s, but there may be.
