What is the recommended/best RPM when the car is idling or in park? I got a 1994 Pontiac Firebird (3.4 V6, automatic) and after I had my AC recharged, it's idling at around 1500 RPM, it used to idle at about 800
RPM. The mechanic said that the "computer is re-learning how to handle the AC and that I need to drive the car for a few miles". Is he right? How many miles is "a few miles". Is the car in any danger?
Thanks in advance.
