02 Bugeye with an issue

[DannyG]

Help. As the title states I have an issue with my bugeye. At idle the RPM's spike to 2200 RPM and drops back to 1000 RPM, Back to 2200 RPM, drops to 1000 RPM. Once I put the car in drive it runs like a spotted monkey and shows no signs of the spike but in the driveway, stop lights, etc she spikes. I have around 89k miles on her and the car was parked for about 2 months due to a knee injury. My question is, is the spike due to the car being parked for an extended period of time and will pass when driven, or do I have an issue. I am not asking for a miracle just some good advice. I now without seeing the car there is no way to tell for sure. Thanks for the read and an advice.

here is a link to how to clean your idle control valve, maybe thats the problem. If you choose to do this make sure to have an extra gasket. Cleaning And Reattaching The IACV (Idle Air Control Valve) - NASIOC

Do you use any kind of engine management?

Nope, everything that is installed was there when I bought her and I have had her for a year

Do you have any CEL's kicking on? A good ol ECU reset could do the trick. Disconnect negative battery cable, hold down bake pedal for 30 seconds, reconnect, then start her up.
