Help 7.3 missing, no codes, did buzz and contribution tests
My truck just decided to run horribly, when I shut it off.
Started missing, seemed like one cylinder but could have been 2, not real sure.
No power, 300 to 400 degrees higher EGT's, didn't seem to smoke any more than usual.
I took it in to Ford Dealer to get a scanner on it. They did a code check and came up with nothing. Said the truck was missing. When they did the Buzz test every injector was fine. When they did the contribution test, they said that #3 and #8 were only at 80%, but still no codes in computer.
No SES light either, at anytime.
Does anyone have any ideas?
