I don't know what else to realize but acknowledge it help to the dealer. I know I've got the shop foreman dynamic upon it at the dealer, but I still feel its pushed to the back as its pass and everyone loses in this situation.
past I begin the car, the engine surges going on in the middle of 1200 and 2000 rpm assist and forth. I misused the IAC and the TPS considering no bend in symptoms.
