Last weekend I finaly got my svt UIM, LIM, TB, and MAF. So I brought it back to Ames from Des Moines and loved everything about it, no problems, but saturday night after performing the TH fix the cel lights. got out reset the computer, no problems again, about 3 Hrs later it comes on again so I take the fix out and drill the hole a little larger, no problems again. Last night I go to work and while on a delivery the cel comes on again, so I take out the fix altogether and reset the computer again, 2 Hrs later it comes on again. So I'm wondering is the MAF bad or am I looking at another problem?
