probably more I cant think of right now.
drove to the next town and back about 95mi roundtrip. truck ran fine.
went to the store later that night, truck had about 3 hour rest, ran fine to the store. went inside and left it running, came back out 5mins (at the very most) later to a rough idle. a little throttle cleared it up. made it home fine, still idling rough. showing cylinder 7 contribution balance code.
this is my daily driver, so the next morning had to take my daughter to a doc appt. ran fine when I started it, about halfway there it began to run rough again. probably 20 minute trip across town (Amarillo,TX). when we reached to doc office truck was running horrible. super rough.
left the doc office and it didn't want to accelerate. tons of black smoke. light gray on idle. it got so bad that I had to hold it to the floor, truck would poor blacksmoke out the exhaust, would barely move, then come back to life.
as soon as you let off it would do it all over again.
underboost code, still cylinder 7 cont. balance.
took me over an hour to get home but I made it.
then a no start.
let it sit for a couple days while I was at work. finalyy got it to start. now cylinder 1 and 6 circuit high code.
cleared the codes while running (using AE) came back with cylinder 1,3,6,7 circuit high and cylinder 5 cont. balance.
ran it for a few minutes and then it was just 3 circuit high.
Ficm main was 48v logic was 13v
fuel psi is 68
icp looks normal.
tuned back to stock
idk whats going on, this is my DD and I really need to get it back running.
Any ideas whats going on?
