So thanks in advance!
Got a 99 f350, 7.3, 4x4, repo truck with power issues.
Seems to idle fine. Seems to run good on flat ground, in the city. Take it uphill, struggles. Get on the highway, struggles to get up to speed. Put a repo on the back and struggles badly at both, though still seems good on flat ground stop sign to stop sign.
Getting on the highway she really bogs down just before 2000rpm, sometimes throws a few white puffs out the tailpipe. Back off the throttle and ease her up to speed seems to help. If I gotta climb a long hill, be lucky to get to the top at better than 10mph(highway or city/loaded or unloaded).
Had Ford run diagnostic, pulls codes for "low oil pressure at injectors"(under load) and "low boost". No check engine light, no injector codes. Before I took to Ford I changed oil, air filter and fuel filter.
After Ford, I checked oil again(good), unplugged, cleaned and replugged all corresponding sensors.
~Oil switch unplugged: no check light, no oil pressure gauge, ran same.
~Oil temp unplugged: Check light on, ran like crap.
~High Pressure unplugged: Check light on, ran the same.
~Exhaust Backpressure unplugged: No check light, ran the same.
~Cleaned sensor above the red and green "wastegate?" lines.
I cleaned all the above mentioned, along with injector plugs(in the valve covers). Drove and truck ran much better. Was able to climb hills fine. Just unable to stomp on it. Still wanted to bog down around 2000rpm and throw white smoke.
Sorry for writing a book! Just wanted to cover everything. Dont know much about diesel motor's. Thanks for any ideas.
