Pinned but wont go! (Tricky lots of details)
Hey Everyone, new member, but been reading on the site for a while now to figure things out through other peoples troubles.
'01' 2wd F350 7.3L Stock with Auto Trans and Dual rear
Recent work - all since problem began, all to solve problem
Changed Fuel Filter
Changed Air Filter
Full Transmission Rebuild (Fall River Ford, MA) based on their recommendation
#8 & #3 Injectors replaced based on diesel fuel shop suggestion
Checked Wires through Valve Covers to Injectors Twice
Truck runs pretty good around town (under 2200 RPM). Get about 15MPG, no rough idle, no knocking, no shaking. If I bury the pedal from a stop or slow role, truck makes it through first fair, flattens out in second, sometimes third & wont shift. Just a complete loss of power and acceleration. If it does shift the trucks shifts hard. Hangs out around 2800 - 3000 RPM
Highway, again if I keep it down around 65 mph, so the RPMs stay low 2s the truck runs fair, at least for a couple of hours. If I try 70, i'm lucky to get twenty mins before the truck stops pulling its own weight up a tiny incline. She will shake, start knocking, and lose speed as fast as she can with the pedal buried. I stop losing speed at about 45 - 50 mph. The truck just needs to sit, either at idle or off. Ten mins or so & I can go back to 65 mph driving for hours.
On another note, last night I felt as though my temp gauge may not be reading correctly. It stays just below half ALL THE TIME. The gauge does not show any numerical value so I don't know how hot that would be. But when I got home I opened the hood and touched the shock holding the hood. It seemed very hot, everything seemed VERY HOT. Hotter than I would figure to be normal and it was not running well at the time.
Maybe a ECT problem or Engine oil Temp Sensor sending bad info to PCM? How would I check that?
The check engine light rarely if ever comes on. It wont stay on more than 5 mins unless I hammer on the truck. I did get it plugged into my OBD reader once with it on and received NO CODES. Very discouraging...any suggestions would be greatly appreciated.
Thanks Guys - Brenden
