Slow Return to Idle
I've seen other posts on this, but I need a lower level introduction (I don't know the various controls).
Truck: 1998 Ranger 3.0L, 5-speed, 130K miles, never any real problems
Problem: After it warms up, the engine speed will hang at 2000-2500 rpm when I push in the clutch. It eventually gets back to normal, ~1000, but it could take 5-10 seconds. It doesn't seem to do it much when the engine is cold. This makes me think that the temperature sensor is whacked and sending a wrong signal to the computer. I know there have been other possibilities mentioned, e.g., the MAF and some other controller (?).
I'm willing to pay Ford to fix it, but I've had terrible luck with Ford dealers, e.g., $85/hr for on-the-job training. If they fix something that wasn't broke, well that is my problem. I hope you can help me zero-in a bit on the problem - and maybe it will be something that I can fix with the few tools I have with me now. (I'm working away from home for the summer.)
