Catalytic converters can go bad and potentially plug the exhaust, hurting engine efficiency and performance.
Ford F-350 Problem Reports
Most Reported Ford F-350 Problem Reports
Failure to change the power steering fluid can cause the fluid to become gray with metal particles. The contaminated fluid can damage the power steering pump resulting in a growling noise when the wheel is turned; the damaged pump will require replacement to eliminate the noise.. Life of the power steering gearbox and pump will be shortened if the fluid is not serviced regularly.
The engine oil pan gasket can develop a leak. Leaking oil may accumulate on the exhaust system resulting in a burning smell. Replacing the gasket should correct this leak.
A ticking noise may develop from the engine due to a warped exhaust manifold. Damaged exhaust manifolds will require replacement to correct this issue.
The tachometer sensor may fail; if the tachometer needle jumps around and the transmission has harsh shifts or does not upshift, this sensor should be checked. This sensor is mounted in a cover at the front of the motor.
The FIPL (fuel injection pump lever) sensor may fail. When this sensor goes bad, shifting is erratic and the Check Engine Light should illuminate. Proper adjustment of this sensor (when replacing it) is a must or the problem will continue. See service manuals for proper adjustment of the FIPL sensor.
