2001 Buick La Sabre Limited's RPM gauge drops to zero while driving?
My Buick's rpm gauge goes from working just fine to 0 in a matter of 20min. The car jolts a little bit when this happens and used to turn off completely while waiting at a red light/stop sign/idling. Can someone help me figure out whats going on?
Ive replaced the following:
Spark plugs/wires, fuel filter, serpentine belt, MAP sensor, Battery (brand new and 200$), gasket seals, oil change.
Is this a good question?
