hello i have a 2000 ford ranger with 2.5 4 cyl 2wd when i shift through the gears the engine revs very high
(3000 r.p.m.), when i push in the clutch, even if i push it in and coast the initial reaction is to rev high then level off when i come to a complete stop. i have replaced the idle air control and the throttle position sensor if anyone knows what could be causing this i would greatly appreciate it

There is a service bulletin on this condition. Replacing the TPS itself may not be enough; it can be a bad electrical connection at the TPS connector. There is a service kit from Ford that will probably fix this condition.
I have listed the service bulletin from the Alldata motor vehicle information website below.
HIGH IDLE - TAURUS WITH 3.4L SHO AND RANGER WITH 2.5L AND MANUAL TRANSMISSION
1998-1999 TAURUS SHO
A high idle may occur on some vehicles. This may be caused by a poor electrical connection at the wire harness (-12B637-) to Throttle Position Sensor (TPS).
Splice into wire harness (-12B637-) just after the TPS with TPS Connector High Idle Service Kit. Refer to the following Service Procedure for details.
Verify the concern vehicle exhibits a "high idle" condition when depressing the clutch or shifting between gears for the Ranger or when shifting between Park and/or Neutral for Taurus SHO. If high idle condition is not exhibited, proceed with other driveability diagnostic fix procedures. If condition is present, obtain a High Idle Service Kit (XF1Z-15K607-AA) and proceed by following the instructions found within the service kit.
