Hey guys looking for some feedback on a truck it's a 2005 6.0. it has a rough idle and misfire under normal acceleration but clears up under full throttle. I pulled codes and has quite a few.
P0261 cyl 1 injector circuit low.
Po266 cyl 2 contribution/balance fault
Po267 cyl 3 injector circuit low
Po270 cyl 4 injector circuit low
Po273 cyl 5 injector circuit low
Po276 cyl 6 injector circuit low
Po278 cyl 6 contribution/balance fault
Po279 cyl 7 injector circuit low
Po282 cyl 8 injector circuit low
Po341 cam position sensor circuit
Po404 erg performance
Po528 fan speed sensor circuit no signal
Po611 FICM performance
The truck has all these codes but no check engine light. Started running rough one night snow plowing at about -10 degrees and though it was gelling. Put in some anti gel and then changed fuel filters and oil a few days ago. Also added hot shot with no luck. Tried to unplug ICP sensor but still runs rough. Any help is greatly appreciated. Thanks
