Vehicles equipped with a 4 cylinder engine may develop a no start or stalling condition, most commonly caused by a failed distributor pickup plate.
1991 Dodge Spirit Problem Reports
Most Reported 1991 Dodge Spirit Problem Reports
A noise from the rear suspension may be noted at slow speeds over uneven road surfaces. This can be caused by a cracked or broken rear torsion bar. A damaged torsion bar will require replacement.
Erratic operation of the speedometer may be noted on vehicles equipped with a passenger side motorized seat belt. This is generally caused by a failed Passive Belt Control Module (PBCM). Our technicians tell us that if the speedometer functions correctly with the PBCM disconnected the PBCM should be replaced.
Automatic transmissions can exhibit a variety of shifting and noise concerns due to failure of internal parts. Our technicians tell us that a complete inspection of all internal parts should be performed if the transmission is disassembled for overhaul. Numerous updated part are available for this transmission.
The fuel pump may fail resulting in a no start condition. Our technicians recommend replacing the fuel filter whenever the fuel pump is replaced. Failure to replace the fuel filter may cause the replacement pump to fail prematurely.
A dirty throttle body can cause a low idle speed resulting in a stalling condition. Our technicians recommend cleaning the throttle body at 15k intervals to help minimize this condition.
Alternator pulley misalignment on 4 cylinder engines may result in belt noise and/or the belt "walking" partially off the pulley. Our technicians tell us that replacement of the AC and alternator mounting bracket, alternator belt, and if necessary, installation of washers to align the alternator pulley may be necessary to correct this issue.
When driving through deep snow the serpentine belt may be forced off the pulleys. If pulley alignment is found to be OK a shield is available to prevent snow from coming in contact with the belt.
4 cylinder engine timing belts can be affected by driving in very hot climates. Our technicians tell us that replacement should be considered before the recommended 60K interval. Replacement timing belts have been designed for greater durability. It is also recommended the belt tensioner be replaced whenever the timing belt is replaced.
4 cylinder engines may develop a cold engine knock that may last for 3-5 minutes and is often mis-diagnosed as a lifter noise. Our technicians tell us in most cases the noise is coming from the piston area and is not a reliability or durability concern.
Engine oil leaks may develop from the following areas: Valve cover gaskets, cam plugs at rear of the cylinder head, cam seals, front crankshaft seal, and the oil filter bracket. Leaking seals and gaskets should be replaced. Due to mis-machining of the mating surfaces, as special gasket is required to correct the oil filter bracket leak.
An exhaust leak and/or chirp type noise may develop from the exhaust manifold to header pipe connection. Our technicians tell us that replacing the exhaust seal ring and flange springs, along with sizing the header pipe flange will generally correct this concern.
4 cylinder engines may develop one or more of the following concerns: Erratic idle, hesitation, and lack of power. Common causes include: Faulty throttle position sensor, brittle or broken wires & corroded or spread terminals in the engine wire harness, cracked or swollen vacuum hoses, and oil contaminated o2 sensors. Our technicians recommend a complete inspection including diagnoses of any stored fault codes if these driveability concerns occur.
Hard starting, rough idle, black exhaust smoke, or poor fuel mileage may indicate a fuel leak from the area of the fuel injector. Our technicians tell us that in most cases the injector o-ring is the cause of these leaks.
