Hey guys I installed the mac offroad header kit for my 99 ls1 and hooked everything back up properly. Then a couple of days later my service light finally decides to pop up. Any ideas as to what might be causing it? Please help me out on this.

 

go get the car scanner to get a code number. do you have o2 sims?

 

i have a pain, it's someplace in my body between my head and my toes....what could it be??



there is NO WAY to figure out what could be causing it without know ing what the code is.
i would venture a guess it's something with the emissions stuff.

 

I bet he knows what pain between his head and toes that you are!
