7.3 Surging, Please Help
I own a 02 F 350 7.3 with 55k miles. It started surging/bucking a little @ 51k and I have changed the fuel filter twice thinking it was water with no luck. I also drain the fuel bowl every few days with no luck. I seems to be getting worse. I only notice it at 30-55 mph when holding constant speed or when the c/c is on...Any help??? Any ideas????

Best thing to do is to get it scanned for codes. That aside, sounds a lot like a TPS. (Throttle Position Sensor). Basically your pedal assembly as a unit. It's self contained and must be replaced as a whole unit, from what I hear.

It's pretty amazing how much can be stored in the computers these days. The carmakers try and conceal as much as they can from the average owner. I think thier logic is that they don't want to be inundated with service calls: "Whats this light and what does it mean?" But the mechanics have access with the scanner. If there is a problem then the scan points them in the right direction. We'd be lost with them. Too much computer control to do so otherwise.
Good grief, where'd all that come from???

[B]Thanks, from what I have read you are correct. My truck has 55k on a 02 would the TPS be under warranty? If not how much do they cost? Also where is it located? and can I change it myself? Sorry for all the questions..Thanks in advance Richard
