You will have to get the code read from autozone or another auto parts store before we can really pin point anything.

Ok I will get it read tomorrow and post the code. The car is running fine I just dont understand why changing the mufflers and not altering the cats would have made the light come on. The throwout bearing starting squealing on it Friday! Geehzz its one thing right after another!! haha

Re: The Service Engine Light Soon light is on!! HELP!

I had the code read yesterday and it was P0442. I figured it was the gas cap or something so I checked that and took the negative cable off and reset the computer. It stayed off all last night and all today until I was on the way home from work this afternoon and its back! Would changing the mufflers have anything to do with it? I didnt change or mess with the factory cats, I just welded up 2 Flowmaster 2 chambers! Thanks

no, most people that have this code replace the gas cap and it fixes the problem, if there is a small leak in the evaporative emissions system it will trip this code.

btw, check the cap seal and around where it seals on the car.

I bought a locking cap from autozone and never had that code come up. Some say buy a dealers cap. when you tighten your cap does it have the clicking action and does it seem to seal good?

It just clicks once. I cant really tell if it seals good! I never really paid it any attention honestly. I have noticed that it only clicks once and not like a regular cap!

also, was the mufflers welded or clamped, just thinking if the sparks landed on a fuel vent or something like that, it requires only a small leak to trip this code.

The mufflers were welded on.

Check the grommet around the fuel filler neck on the passenger side of the car. Also inspect all the hoses and rubbers around that area for leaks. If they were cutting, wiggling and welding pipes something may have gotten caught, burned, knocked loose. I have that same code and my filler neck grommet is leaking bad.
