Ok. I had a real bad misfire a few weeks ago. I changed out the plus,wires,and coils. Since then a new issue seems to have developed. When the car is first started and driving it runs fine. Once the engine warms up the car starts acting like its misfiring. It bucks a little and it doesnt want to accellerate. It has a smell like methonal, it reminds me of the smell from the methonal fueled cars from the track. I am not getting a check engine
light (i know its just a dummy light). Does this sound like the effects of a clogged catalytic converter? The exhaust sounds like it is putting like maybe something is clogged. Ive never had a car with 2 cats so could this be just one cat clogged? any help would be great. Thanks guys.
