The engine temperature sensor wire for the engine temperature gauge, or warning light, may touch the rear exhaust manifold causing a short to ground causing erratic operation of the temperature gauge or warning light.
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.
The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.
The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.
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.
The high pressure power steering hose will commonly leak fluid; it should be replaced.
The spark plugs should be replaced every 30,000 miles and the spark plug boots should be checked for hot spots and cracks.
