[tintoy]

Hi i upgrade my gvr4 jdm 88 model. 16g turbo, 609 maf, evo4 fuel pump, 510cc injectors and evo3 fpr. In idle Check engine indicator is on, when i rev it the indicator turn off. Any suggestions? /ubbthreads/images/graemlins/confused.gif

My first guess would be TPS. A bad TPS will often behave this way.

You could also try clearing the codes by unplugging the battery for a min or two if it still comes on again then somethings up. usually when the check engine light comes on my car I have a friend of mine plug in his scanner and its usually some kind of sensor ask a few shops see how much they'll charge to scan you're car might be worth a try if you can't find the problem.
