My Stang: 94 GT convertible. 58k. Mods: shifter, C&L intake, BBK 65mm throttle body, OR h-pipe.
Problem: starts well, shifts well. I replaced the IAC with Motorcraft, as nothing else did the job right. The TPS was replaced with BWD part, as I cannot find a FORD part. When I am in reverse and come to a stop, the idle drops below 500, but then recovers. It will do this a little less noticeable in forward gears. Otherwise, everything works well. I do notice that when I come to a stop, the engine will attempt to drop idle, but it pulls back to the proper idle speed and will run smoothly. Is this normal, or do I have something that needs attention? This car is quite nice for it's age. Garage kept and never driven in the rain. All the hoses look new. No dry rot. I changed the IAC, as it was sticking. The TPS was changed at the same time. The first TPS was from NAPA: ECHLIN. The idle would not go below 1k with that one. Wondering if what is happening now still due to TPS. Any help would be appreciated.
