Known Problems

Usually by 150,000 miles the AC system will need some attention, especially in climates where it is used often. Our technicians tell us that it is best to service the AC system every 2-3 years. This keeps the moisture in the system at a minimum which extends the life of the components.

Some of the fuel/temperature gauges fail and read maximum at all times. Our technicians tell us that there is a gauge cluster replacement that includes the little voltage regulator as well.

The idle air control motors tend to become carboned up at around 100,000 miles and can cause a start and stall and/or stalling at stop sign problems. Our technicians tell us that many times these motors can be cleaned, however, the sure bet is to replace the idle air control motor and clean the throttle body.
By 100,000 miles the ignition key tends to wear out and should be replaced or it may not work as well in the door locks or ignition switch.
