Need you help guys, I'm really starting to get annoyed with my GT. Here's what I'm dealing with. For the past month, the revs go up 3-400 RPM between shifts and or/ kinda hang in between shifts. Another issue I had since I bought it was more often than not the car would start and stall unless I gently held the throttle down for about 30 seconds. This would happen 95% of the time when the car was hot and then sat for 10-15 minutes. It's done it to me a few times on cold start. I figured it was the IAC valve at this point. So I bought a new Motorcraft piece and installed it along with a nice Ford Motorsport 65mm throttle body I scored. Besides a nice noise when I give gas, symptoms have not gone away. :undecided: If I unplug the TPS or the IAC the revs drop as soon as I push down the clutch. I went for a rip yesterday and she feels down on power as well. Here is a list of all the parts I have changed on this car. Everything is Motorcraft unless stated - Spark plug wires - Spark plugs (NGK) - Cap and rotor (MSD) - Coil - ECT - ACT (Standard) - 02 sensors - Fuel Filter - IAC valve I swapped the MAF with a spare I had lying around, didn't notice any difference either.
