One needs to know the year and model of the car, and whether 8 valve or 16 valve. One thing to check first is the small motor valve (the AIC) near the front of the engine. It bypasses air across the throttle. It is common for it to stick, needing cleaning. The hoses attached to it can be looked at also.
