1993 Buick Roadmaster fuel filter

If your car is fixed by now, Happy Driving. If not, a general tune-up should take care of this problem. However, have your technician to pay close attention to the PCV system (check it to make sure its working well). Sometimes it becomes clogged and has to be cleaned out so that vacuum can be felt at the end of the PCV vale when the engine is running. Also have the injectors and throttle body cleaned. Hopefully this will help. If you still need it.
