Car was sitting for a little bit, but back up running now. Rpm's jump up and down consistently a few mins after starting. I know with the car sitting for a long period and there's lots to do but I want to narrow my options down. The radio stopped working and the AC is stuck in the on mode currently, Im not sure if that could have something to do with it either. Do you think it could be related to any of these listed below?


A. Spark plugs and coils

B. Dirty throttle body or air filter

C. AC/Radio

D. All of the above





Thanks in advance

 

hey there, sounds like a frustrating situation. i'd start with checking the spark plugs and coils, they often cause rpm issues. not sure about the radio/ac connection, but it could be electrical. good luck!
