    Cam sensor?

    Found out, I replaced the cam sensor only to have the same problem. I hooked up a scanner and cleared the codes. It passed a buzz test and everything. I messed with the cam sensor and it started working just fine. So I'm gonna replace to pigtail, clear the codes one more time and see if that...

    Cam sensor?

    I started my truck just fine and as soon as I would press on the pedal it would go almost like it had a lope tune. Hardly wanted to idle. As soon as I would let off the throttle, it would go back to idling normal. I have a video that I'll post later

    Running with front hub partially locked

    I'm not completely sure on your truck, I have an 01 with auto hubs and tcase. I'm not sure if they changed much. I just saw no one has replied to this form so thought I may try and help. I had an issue on my truck where a grinding noise was coming in when I drove past a wall. Turns out the auto...

    7.3L Miss at Mid-RPM

    On my truck the sensor itself had a leak and oil was all over the pigtail and in the valley with easily noticeable oil tracks from where the icp plugs in. On the other truck I e encountered icp issues with, it was not the wiring itself, the the male end of the plug had bent guts so the...

    7.3L Miss at Mid-RPM

    I know my truck had a rough idle when the icp was on its way out but my truck did the opposite of yours, it would run rough when the truck was cold and it would warm up, CEL would go away and it would run nice and smooth. I'm wondering if there is not an issue with a wire between the Pcm and icp...

    7.3L Miss at Mid-RPM

    No the truck would see that dead spot and go into an idle only mode. It wouldn't let you rev up the truck at all regardless of park, drive, or reverse. It seems to be a common occurrence. the only way i would imagine that it would cause a buck/miss would be if there were two dead spots at...

    7.3L Miss at Mid-RPM

    Also from what I understand the tps (throttle position sensor? Is what I'm assuming) has a built in fail safe for things like this. Because the diesels do not have throttle plates to limit rpm. So the engineers decided they needed a fail safe in the tps. They made it so that both sides of the...

    7.3L Miss at Mid-RPM

    The torque app is just a monitoring system. It shouldn't have any bidirectional control over the pcm. Like for example a scan tool could activate computer controlled stuff such as turning on a horn or activation of a relay. The torque app and its hardware will only let you view certain engine...

    Truck cranks but no start

    11.9 volts is not a good number. It should be 12.6 for a good battery. Charge them up and unplug the charger. Leave them alone for a little wile. Then make sure they still read 12.4 if they do then they hold at least 80% of maximum capacity and should be okay. Next you could put them in the...

    Questions on buying used 7.3 HIGH MILES

    IMO 14500 is to much for 380000. I had a 94 5.0 f150 up until last summer before i bought my 7.3. I wanted diesel very badly as well as I wanted something that was OBDII but not too new that parts would be so expensive. Im in Utah and in my area not only couldnt I find a normal mile 7.3 for sale...

    EBPV exhaust brake

    Yea I have read many other forms on doing it on auto transmissions. That's why we did it on the manual truck first haha. Thank you though, it would be terrible to throw my transmission overboard. The primary reason I made this thread is to share my wiring diagram.

    EBPV exhaust brake

    I'm pretty new here, so this is my first post. I really appreciate the community. Hope you guys find this helpful. Im doing and exhaust brake on my fathers 99 7.3 with the ZF6/manual tranny.
