Volvo: Volvo 960 speed motor, vacuum leaks, andrea andrea

Question
Ray,
The Volvo is hesitating when accelerating. Has been to Volvo dealer, , found idle speed motor seized, was cleaned out but next next day we found the same problem. Do you think this can still be the speed motor or something else?
THANKS VERY MUCH!!
Andrea


Answer
Andrea,
Might still be the idle motor, are there fault codes for that? I would say there are more problems then just the idle motor. Hesitation really does not have anything to do with idling. Check for fault codes and vacuum leaks, engine miss, tune up, fuel filters, timing, low fuel presure, clogged injectors, bad gas.
