I have a 1994 Crown victoria that while it idles it revs its self up. It doesnt rev high just like it has a lope in the idel. I replaced plus,wire, air filter, vac lines, etc etc etc. It does not hurt the car but man does it soud like crap when its runnning. This car has the police package and has 205k on it and it still gets mid 20 mpg. This runs strong and dont want to change the motor or anything due to this stupid problem. Oh and i forgot there is no codes and not a SES light. Could it be due to the A.C. leaking somewhere?????? HELP!!!!!!!

 

whats the rev at idle?
