1993 Mitsubishi Precis ProblemsDriveability Issues Due to Faulty ECM Ground
A faulty engine control module (ECM) ground circuit may cause various issues including stalling, loss of air conditioning operation, and illumination of the Check Engine Light. Our technicians tell us that adding another ground wire to the ECM wire harness can often correct this issue.
The coolant valve under the right side of the dash may develop a leak. This can easily be mistaken for a leaking heater core. Our technicians recommend careful diagnoses of coolant leaks in the area.
The manual transmission may become difficult to shift into third gear. This is common caused by worn synchronizers. Our technicians tell us that revised synchronizers are available to correct this concern.
