replaced
The problem was when I start my truck up in the cold mornings, it starts fine and runs at a decent idle (low but idles) when I put into gear (auto drive) the rpm's shoot up, a few hundred rpms, any how I drive it around till warm and go to put it into park it dies, so I replaced the IAC (idle air control) but it still does the same thing, so what next would be in line to check/replace? I have a 89' f250 with a EFI 460 and an unadjustable timing system (so im told it does it automatically by the readings and comp).

This all started happening after I did the tune up (including a new O2 sensor) and no did'nt disconnect the battery after installing the IAC (was I supose to?) Will try it and see what happens. So any other ideas if that does'nt do the trick?

plats and these engines do not play nice.
use motorcraft copper plugs.
i bet your plugs are fouled and are the source of the problem.
does not take much for that little ity bitty tip to mess up.

I thought motorcraft and autolite were the same thing. I have always ran motorcraft or autolite platinum plugs in my truck. Its got 250K miles on it and I've probably put in new plugs about 4 times. The very first time I changed them, I put in the regular motorcraft plugs. It ran fine, but they didn't last but about 15-20 K miles. I don't want to have to fool with them that often. I've never had a single problem and they last longer than the regular plugs. I have heard though that alot of people prefer the regular motorcraft plugs. Stay the hell away from all the types of Bosch plugs though.

My bad, I have got to remember when replaceing parts that have a plug on them, that I have to DISCONNECT THE BATTERY and reset the computer, once I did that and drove it around, enough time for the computer to recaliprate the system. Thanks ya'll
