Idle Problem Recent Heads cam swap
Idle Problem Recent Heads cam swap hi guys having trouble with the car idleing when its cold. recent heads and cam swap. its a 99 ws6 m6 mods are sig but the biggest problem came after the cam and heads, its a 228/230 .600 lift, lingenfelter take off heads and a IAC valve and a speed density tune. When i start it from cold it wont idle i have to keep the gas on it just to about 1100 rpms until it starts to warm up and as it warms up it will start to idle but it will bounce from about 600rpm to 1000rpm and eventually as it warms up, it will idle fine any ideas
