I'm having i few issues mainly idleing and(M6)when i push in clutch the rpms shoot up say if i'm at 700rpm coming up to a stop push in clutch and the rpms shoot up to 1400 and if i'm in neutral and the car is moving the idle like hangs at around a 1000 rpm intill the car is completly stopped then it tries to go to programed idle which is 800 but can't get there. The idle goes up and down from 600 to 1000 consintly. It does not do this at cold start up. The ilde stays steady untill it warms up then the idle starts acting up. If i can get any help that would be great. I'm a newbie. My eyes are hurting from reading so much tuning stuff i don't even know how to go to the bathroom now I'm so confused. If it correlates with my idle issue i'm getting knock around 5000rpm and so i let off the gas, and it surges between 1000rpm and 1300rpm if trying to maintain a certain speed like looking for a parking place in a mall when you creep around waiting for a spot. The car surges and people thing i'm messing with the gas pedle because the car is lurching. Embarrassing.
