1990 Mitsubishi Eclipse Problems
The engine may stall or develop a rough idle with the Check Engine Light illuminated and fault code 15 stored in the ECU. Our technicians tell us that the engine electrical grounds are critical, all 5 should be inspected and cleaned as necessary. An additional ground lead kit is also available which can be installed to help correct this condition.
The 80 amp fusible link for the charging system can fail and is often overlooked when diagnosing a charging system that is not working. Our technicians recommend to make sure this fusible link is OK before replacing any charging system components.
The manual transmission may become difficult to shift, this is commonly caused by binding between the synchronizer and the gear surface. Adding a special friction modifier to the manual transmission fluid will often correct this condition. If the problem persists revised synchronizer kits may be available.
