Stalling at Idle

[The Fuzz 53]

I have a problem with my Ranger where it will stall at idle. It isn't consistent though. Sometimes I'll have to sit for 2 to 10 minutes and it will then stall, or it will just stall when I let off the gas. And it appears to happen more frequently when it is cold outside.

First off, it's a 1995 Ford Ranger STX 4x4, Ext. Cab., 4.0L with Auto Trans. At first, my problem was that I couldn't get the truck to start without putting my foot on the gas peddle. I scanned it for error codes and had one for the EGR Valve. I replaced that and the starting issue was fixed, but then came the stalling problem.

I then replaced the Mass Air Flow Sensor because it appeared to have a burned element and it was dirty, but that did not solve the issue. So I brought it to the Ford dealer and they just replaced the IAC, but that didn't fix it (man am I pissed about that waste of $). My next idea is to replace the Throttle Position Sensor. There are no error codes whatsoever. If that doesn't work, I'm fresh out of ideas.

Sent it back to the dealer last night. They have no idea what the problem is. They say they have a call into Ford for help on the problem and will update me tomorrow.
