1992 Buick Regal ProblemsRough and/or High Idle Due to Engine Vacuum Leak
The upper intake manifold gasket and/or a PCV vacuum lines/hoses can develop vacuum leaks with age. This type of leak can result in a higher that normal or rough idle.
Fuel injectors can short-circuit electrically causing a rougher than normal idle and reduced performance.
The ignition module or crankshaft position sensor may fail causing the engine to die and not restart. Diagnoses will be necessary to determine if the module or crank sensor is causing the no start condition.
1992 Buick Regal QuestionsMy 92 Buick misses somtimes than seems to go away. but now its getting worse .Id like to know if the most likely reason is one of the 3 ignition coils, Plugs,wires, Vacum (1 answer)
58000 on motor One of the ignition coils has been changed That I can see dont see any vac leaks plug wires dont look old
Fitting broke right below hex and is flush with manifold. Inside dia. of plastic is "mushy" outside dia. is still very rigid and stuck in threads. 1"-14 UNS thread
I believe it could be the ignition modular but not sure if it might be either the catalytic converter or my worst nightmare a fuel pump
