ok the truck is an e99 f550 7.3 auto 4x4
Had a fun day with it today, first OD light started blinking, and spedo droped and fluttered, something kicked up off the road and pulled the wires off the rear..
next on my home trip @17140 lbs climbing a 10% grade truck was in 3rd gear pulling hard 40-45mph ish and all the sudden it starts missing bad no smoke at all like it was hitting a fuel cut, (ses light comes on) slow down drop to 2nd and ease up the hill. at one point i held WOT no accelration then boom felt like it was shot out of a cannon ses light goes out accelrates like it should then ses comes back on and im back to a crawl. pull off shut down check over everthing i could all seems fine restart no ses light truck runs ok not the best but ok get home and unloaded run the scanner
buzz test passed
but have a code for
p0275 #5 cyl
p0237 boost cir low
p01249 waste gate perf
p0236 boost psi sens
noticed the wire harness on passanger side of the block looks like someone was stepping on it or twisting it around after i ran the tests took it for a ride got about 1/2 mi out started again thistime ses light on but it acted like it was starved for fuel again no smoke out the exaust. stopped shut down wiggled the pass side wire harness started back up ran better no ses light.
normal blow by for a 7.3 cranks longer than my other e99 to fire. cant find to much history on the truck but it does have a new turbo and from the looks of it they didnt set the waste gate properly.
please feel free to chime in kinda scratching my head? thank you!
