Most reported 1991 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.
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.
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.
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.
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.
A hesitation/stumble or driveway dieout maybe noted when starting the engine cold. This can be caused by carbon deposits built up on various intake components - air flow sensor, air intake hose, air intake plenum, and intake manifold. These components should be inspected and cleaned as necessary. If heavy deposits are found on the intake valves the cylinder head may need to be removed for proper cleaning.
