The high pressure power steering hose will commonly leak fluid; it should be replaced.
The display on the heater and AC control panel may become dim or go completely blank. Our technicians tell us the control panel must be replaced to correct this fault.
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 crankshaft position sensor, ignition module, and/or powertrain control module (PCM) may fail resulting in illumination of the Check Engine Light with ignition system related fault codes stored in the PCM. Patience is necessary when dealing with this specific situation as normal diagnostic procedures are not effective. In many cases, the best option is to replace parts, one at a time until the fault is corrected.
The intake manifold gasket may develop external engine oil leak. The manifold gasket will need to be replaced to correct this issue.
