Hi Guys:
My 2001 GTs Idle was waving about when coming to a stop or going from neutral to drive (auto). So I ordered the 01-04 type IAC valve from 50resto and installed it.
The new piece looks slightly different from the stocker... The stock one has a weird little black plastic cap sticking up out of it, the new one does not (whats that thing?). Also the electrical connection was upside down. The clip only connects one way, so you cant get it wrong, but it clipped on the right side where the stock one clipped on the left.
So I fired her up, and she ran fine. But when I revved the motor there was a clicking sound and when I got off the gas... this tick, tick, tick, tick sound that slowed and then stopped. Knocking??
This gradually seemed to get better. I took her for a drive and it suddenly seemed to be gone. I pulled over and shifted from D to N a few times, and one time the idle dropped too low and it died. I fired it up and drove home. I cant reproduce the problem now and it doesnt die anymore. No SES.
Does the ECU have to relearn the Idle mixture or something? Or do I have the wrong IAC valve? I didnt reset the ECU during the process.
I dont know if this related, but I popped the vacuum line (that goes from the throttle body to the head) off the left head while changing the IAC. I reconnected it before finishing the job by just pushing it back into the top of the head. I couldnt really see under there well, but it looked like it pushed in the hole and didnt connect very well. I pushed pretty hard and it didnt want to go in there better?
