my buddy brought over his $6000 dollar MacTools Scanner, it pulled
P1275- cylinder 5 High to Low side open
P0603
P1316
it also brought up, Cylinder 3 & 8 contribution or balance malfuction
what does this mean^^^^^??
what do the codes mean and what can cause it
the reason i had him scan my truck was becuase i was headed off base and had to go up the pass which is pretty steep, i was 5th gear (manuel Trans) running a steady 2000rpm's. when suddenly the truck jerked hard, i noticed the rpm's dropped down between 1500-1750. i was easy on the throttle till i got to the top, then it ran fine. then a few days later i was on the interstate 5 gear, 2000rpm's. my buddy came up beside me in his duramax, and of coarse we both floored it, i was running 2300-2500rpm's for about 3-5min. then out of no where the truck did the violent jerk 6 times in a row, the rpm's would drop 250rpm's every time it did it. What could cause this. Ive noticed that the check engine light comes on when i lay the pedal to the floor, no matter what gear im in. my buddy said it could be a fuel pump issue. What Do you guys think?
ive just recently got the truck, never owned a diesel before but have been around cummins and duramaxs my whole life
truck info: 2001 f250, 7.3 powerstroke, 6 speed manuel, K&N air filter, Banks Chip that plugs into the CPU (Removed since problems started)
Recent fixes: changed oil, changed fuel filter, changed the TPS and CPS
