Having problems with your Ford F-350 ?
The engine is 7.5 liter 460, it runs fine sometimes and shifts fine and then all of the sudden it starts running real rich and starts shifting really hard. We have replaced the egr valve and a few other sensors, spark plugs, wires and coil.
Did you change the coolant temp sensor and the air temp sensor. sounds more like the coolant sensor is not working right this could cause the computer to dump more fuel which would cause a rich burn and the shifting problems check the leakage on the trans.When was the last trans fluid change and filter?
