1990 Ford Aerostar ProblemsBad throttle position sensors can cause high idle
Bad throttle position sensors can cause high idle without causing the Check Engine Light to illuminate.
The AC system may be performing poorly even if it seems to be functioning properly. This could be caused by the AC air blend door being out of adjustment.
The battery light may illuminate on the instrument panel because the alternator wire harness connector is damaged. A new connector kit is available and should be installed to correct this concern.
