1991 Ford E-150 ProblemsMisfire, Hesitation, Rough Running from Engine, Notably After Ignition Wire Replacement
The engine may have a misfire, hesitation, and/or run roughly – notably after a service and/or ignition wire replacement. If after recent ignition wire replacement, the cause can be misrouted ignition wires. The wires from the distributor to the valve cover must be routed correctly to avoid interference and induction crossfire. Verify all clips are used to secure and separate ignition wires.
Common sources of rear axle leaks are the rear differential cover seal, and / or the pinion seal. Reseal the rear differential cover with the appropriate sealant and / or replace pinion seal for leakage.
Transmission fluid leaking from the front of the transmission bell housing may also be accompanied with shifting and transmission engagement issues. This is often caused by transmission overheating and is the sign of a significant internal transmission problem. The superficial cause is the failure of the front pump seal of the transmission. The immediate repair is to remove the transmission, replace the front pump and seal, replace all fluid with the transmission filter, and verify proper flow through the transmission fluid lines and cooler. It is also recommended to make sure the vehicle is not pulling a load that is heavier than the gross vehicle weight limits because this can cause the transmission to overheat. Depending on the transmission's mileage, this can also be a good time to consider a complete overhaul or replacement with a remanufactured unit, as often just the pump and seal replacement is a short lived remedy. This concern relates specifically to the E4OD and 4R100 automatic transmissions.
