engine revs Sign In

I have a 1999 cougar 5speed, after a while of driving around when i come to a light and press the clutch in, the engine will rev ridiculously to about 31/2 to 4 and then after about 5 seconds it will drop. then when im shifting as soon as i press the clutch it will rev and make the car jerk. Any suggestions as to what can cause this problem. your replies will be greatly appreciated.

Theres are several things that could be causing this trouble....to name a few, idle air control valve/idle air actuator/idle stop solenoid....even the computer,....try some carb cleaner, spray into the throttle body and around the plates even some fuel treatment in the gas might resolve the problem.....other than that a computer diagnostic test will have to be done.Unimpressed
