need some help please..
my friend has an 04 with 150k on it. it started running crappy, no power, hard cold starts, sluggish ect. He took it to the dealer and they said it was the egr valve, they cleaned it and put it back in, but it had little change.
we just got done doing oil changes on both our trucks tonight, (rotella t5).
With all the searching and reading i have done the past few months, i am a big believer in watching the eot and ect's, and we both plan on changing to elc asap!!
He hasn't had any real problems with the truck, just maintenance stuff and this egr issue to this date. original owner so he knows everything about the truck.
no signs of overflow at degres bottle, but we were curious of temps, with how any miles he had and no real issues...
He is going on a few hour trip for thanksgiving so i gave him my edge evolution to monitor his temps.
the edge flashed 4 codes!!
p0275 cylinder 5 contribution/balance fault
p0281 cylinder 7 contribution/balance fault
p0284 cylinder 8 contribution/balance fault
p0528 fan signal malfunction
so we are worried about the first 3, 4th we can check wires and fan not an issue..
what does contribution/balance fault mean?? is this a compression issue, injector issue or what??
what should we check/do do fix/diagnose?
why didnt the dealer find these codes?
Thanks in advance..
