The high pressure power steering hose will commonly leak fluid; it should be replaced.
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 spark plugs should be replaced every 30,000 miles and the spark plug boots should be checked for hot spots and cracks.
Contaminated brake fluid can cause problems in the brake system and it should be flushed every 60,000 miles.
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 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.
