1992 Buick Regal Problems
Engine Overheating Due to Water Pump Leak
The water pump may develop a coolant leak resulting in an engine overheating condition.
Engine Oil Leak From Intake Manifold Gasket
The intake manifold gasket can develop external engine oil leaks. The intake manifold will need to be removed and the gaskets replaced to correct this issue.
Check Engine Light Due to Cam Sensor Interrupter Fault
The cam sensor interrupter (magnet) may become demagnetized and/or fall off of the camshaft gear causing the Check Engine Light (Service Engine Soon) light to illuminate. On higher mileage vehicles it would be advisable to replace the timing chain and gears if this problem were to occur as the timing cover must be removed to replace the interrupter.
Rough 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.
Car Won't Start Due to Ignition Module/Crankshaft Position Sensor Failure
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.
Engine Stalling Due to Mass Air Flow/Crankshift Position Sensor Failure
The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently. Proper diagnoses will be necessary to determine the cause of any stalling condition.
Engine Stall Or No Start Condition
The fuel pump may fail causing engine to stall and not restart.
Transmission Fluid Leak From Cooler Line
The rubber section of an automatic transmission cooler line may develop a fluid leak . In some cases the leaking section of hose can be replaced. In others, the complete cooler line must be replaced to correct this concern.
Stalling or Low Engine Idle Speed Due to Dirty Throttle Body
Body: A dirty throttle body may cause a lower than normal engine idle resulting in a stalling condition. A stalling condition may also result if an idle learn procedure is not performed if the battery goes dead or is disconnected.
High Pressure Power Steering Hose Can Leak Fluid
The high pressure power steering hose will commonly leak fluid; it should be replaced.
Incorrect air flow from dash vents due to damaged engine vacuum hose
Fuel injectors can short-circuit
Fuel injectors can short-circuit electrically causing a rougher than normal idle and reduced performance.
Rubbing noise due to bent rear suspension links
Engine Control Module (ECM) can fail
The Engine Control Module (ECM) can fail causing stalling, and engine and transmission drivability concerns.
