1988 944 Cold Start and Warmed Up - Low Idle Speed

Fuel System

Vehicle Information: Model(924/944/968): 944; Year: 1988; Body Type: Coupe; Total Mileage: 96000;

When first started during the day or nite, or started after sitting 15 or so minutes (following a lengthy drive) my 944 starts up OK yet idles very low, rattling the whole car. After a few minutes, idle speed returns to a steady spec level. God forbid that I turn on the air conditioning during this initial period as the idle drops significantly and the engine feels as though it may break right off the motor mounts. The engines mounts have recently been changed.
