1990 Toyota Celica All-Trac Problems

Our technicians report that 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 lock cylinder.

Over the time the exhaust gas recirculation (EGR) system may become plugged with debris, the oxygen sensor may also be getting slow or 'lazy' around this time. When servicing or cleaning  the EGR system, it is a good idea to replace the oxygen sensor because it works in tandem with the EGR system.

It is important to regularly check the valve clearance as the exhaust valves may become too tight. This will lead to valve failures, which are expensive to repair.
