High idle problems
I have a 1998 Ford Ranger 3.0 4x4 5 speed. I purchased the vehicle w/50,000 miles on it and have had this rev problem on and off since. After the engine is up to operating temp, it will rev to 3,000 on the tach if I am moving and the clutch pedal is depressed. If the truck is in gear, it feels like the truck is trying to push me up to 3,000 rpm range in any gear. When the pickup stops rolling, the idle will come down to normal. This happens more in the summer and also when the pickup has been driven for a long period of time. There is no lights on the dashboard and besides normal maintenance, I have not done any "part swapping" to try to fix the problem. Also, it has 150,000 miles on it now.
Thanks in advance for the help
