hey all hope everyone had a great Christmas!!! I have a 94 gt 5.0 5 speed with 75,000 on the engine, and 241,000 0n the chassis, every time I start the car warm or cold it will idle up as it should then the cel will blink 4 times and the engine will rev up to 2,000 rpms for about a min then crash like you unplug the iac and stumble and sputter for a few seconds and then level out and idle and run great until you shut it off and start it again and then the same thing all over again unless you take off or at least bump the throttle before the cel blinks then it wont do it. The engine is basically stock iac is cleaned and working, egr is deleted and smog is deleted for years, o2 sensors were replaced two months ago, all other sensors were check and spec out ok, tps is good and set right, throttle body and intake cleaned, it has a new motorcraft distributor that I put in about three months ago and timing is set at 12*, fuel pressure is good, no vacuum leaks and up till a week ago the car ran awesome, its my daily driver to work, the car runs great after it does this stunt and the mileage is still good and there are not codes at all I will check for codes none disconnect the battery clear the computer do the idle relearn and drive it for a few days and then check for codes none present 111 on both memories, anyone ever hear of this????
