Having problems with your Mercury Cougar ?

2000 mercury cougar engine speed stays up when gas pedal is release, increase when pedal is release and shifting gears, takes 3 seconds or more to come down to idle when gas pedal is release, will hold at 2000 +- 250 repm when driving and releasing gas pedal and just letting it go, and sometimes, but will drop in rpm if brake is used and gas pedal is release to slow down, and sometimes at a stop light will almost stall dropping to 250 rpm then recovering to a good idle speed of 750 rpm.
