this is my first post of hopefully many to come. my question is about my check engine light. i can crank my car and let it idle all day and it doesnt come on, but when i go down the road about 1/4 to 1/2 mile(sometimes a little further) it pops up. i dont think the car has any 02 sims to compliment the h-pipe, so i was wondering if that could be the problem. i know that i would throw a check engine light. any suggestions would be helpful thanks

yep the 02's is very possibly throwing that light, you need to have it hooked to a computer to read the code and see exactly what it is. Do a intro in the introduction section too, welcome 8)

You HAVE to pull the codes. it could be anything. You shouldn't be using 02 sims on a 5.0 in the first place. There are no cats before them so there is NO need to simulate anything.
