I found the box by the strut tower I think I can find the codes, but how do I know what they will mean?? Will they tell me if the tps is bad or out of adjustment? Will they tell me if the iac is no good?? In my last posts, the car had all kinds of problems, but after replacing nearly everything, the car still has this weird idle problem. Now after it warms up, the idle is really low almost stalling every time i stop. If it doesnt stall, when I try to accelorate from a stop sign or light, when i hit the gas it is pretty unresponsive until i put the pedal almost all the way to the floor, then it bucks and reluctantly takes off. The past few posts tell all the parts I have replaced and what i have cleaned, but does this sound like faulty tps, of iac. WHAT IS CAUSING THIS TERRIBLE IDLE PROBLEM??? Any suggestions??Thanks in advance
