I have 2 inch stainless steel exhaust straight through, with budget intake mods. When I floor the car, the check engine light comes on. is this normal? I am sure there is some simple fix, so please have pity and answer me.

 

check your sensors. you might have one that is not all the way plugged in

 

do you mean O2 sensors? which sensors?

 

What code is it throwing?

 

Yes, give more info. Codes, what mods, what car, etc...

 

peel up the carpet on your passenger side and look at the red light and tell us how many times it is blinking. remember to do this when the light comes on and do not shut off the car or it loses the code.
