1991 Toyota MR2 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 1991 Toyota MR2

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.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.

At higher mileages, (125,000-150,000) the automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.
