1993 Mitsubishi Eclipse Problems
RepairPal has identified the most common problems with the 1993 Mitsubishi Eclipse based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
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 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.
A squeal or squeak type noise may be heard from the rear brakes on application. Our technicians tell us there is an updated rear brake pad shim kit which can help reduce this type of noise.
On 2.4L 4 cylinder engines a whining noise may be noted when the engine is cold and the rpm is in the 1800-2000 range. Our technicians tell us that most commonly this type of noise is coming from the engine oil pump. The repair is to replace the front case assembly and both the drive and driven oil pump gears.
Carbon buildup on the top of the piston is common. Over time this can lead to symptoms varying from light ticking to knocking noises. Performing a fuel injector cleaning procedure can often help the condition by removing some of the piston top deposits.
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.
A driveline vibration may be noted on smooth roads. If the occurs all driveline mounts should be inspected and replaced as necessary. Upper and lower radiator mounts should also be inspected in the same manner. If all mounts are good and the problem continues updated engine and transmission mounting brackets are available which may help this condition.
