99 F-350 Diesel Cutting Out Under Load
My 1999 F-350 diesel w/ 200k cuts out under load at a certian position in the gas pedal. It has a six speed in it but it is almost like it is looking for the passing gear. I bought it used so it could have a different computer in it I guess. If you push down farther or let up on the pedal it takes off just fine. Is the a way to bypass a passing gear on the computer?

Re: 99 F-350 Diesel Cutting Out Under Load
I would bet that the pedal switch is going bad. I don't know how to test to see if it is, but i'll do some more research. About what RPM does it cut out?

Re: 99 F-350 Diesel Cutting Out Under Load
Do you have any check check engine lights? Couple of things to look at would be the CPS. A friend of mine also said that his was cutting out because of a loose connector on the valve cover.

TRY cps first but most likely the throttle postion sensor, You will have to replace the pedal assembly if its that, which I bet it is.
