Hey guys,
My 06 F250 (6.0) has started acting up on me in the last few days and I hoped that I could get some advice on where to start looking for the problem. I was moving some trailers the other day and she was running just fine but as I got off the interstate and stopped, I noticed something wasn't right. The engine started running rough and it sounded like it was missing but it didn't throw a code and a minute or so later it smoothed out again. The next day I started it and let it warm up and it sounded fine but as soon as I started driving it sounded like it was missing again and it didn't want to shift. After a few minutes, as I was trying to accelerate, it smoothed out again but as soon as I stopped it would start running rough again. After shutting it off and starting back up again, I got an engine light, P0279- (Cylinder #7 injector circuit low). I cleared it to see if it would come back up again but it didn't and for the rest of the day it ran fine. The next day, she was back to running rough again and the light was back on, so I know I definitely have an issue. In addition to the P0279 code I also now have P0281- (Cylinder #7 contribution/balance) which I believe is probably due to the previous code. I have been reading up on the problem and it seems that the issue is likely electrical. I sent my FICM in a few years back to FICM Fixer and he went through it for me, he offers a lifetime warranty on the FICM voltage and I'm guessing that's not because he enjoys fixing them over and over, so I don't really think that I have an issue there but I could be wrong. I was going to start my search by looking for chaffed wires but I was wondering if anyone could give me any clues on the best places to look for wiring issues with injector #7. If so, I would much appreciate it. I have been fairly convinced that I have an electrical/wiring problem from the way the problem would start and stop as the vehicle bounced around, but I suppose that could also be a fuel related issue. I had forgotten up until now that before I filled the tank up and these problems started, I went out to the property that I just bought and I forgot to check my fuel beforehand and the fuel light came on just as I pulled in the driveway. It was late at night and the only gas station within range was closed so rather than staying the night in my truck and waiting for the gas station to open, I drained some fuel out of the excavator that I just bought. When I filled the excavator I put some of that Lucas Fuel Stabilizer in it, which I don't normally use but I found a gallon that I had from awhile back and figured "what the hell". I am thinking now that the problem could also be a result of contaminated fuel from the excavator, running the tank almost empty, or maybe the fuel treatment actually broke some stuff free and clogged the injector. Let me know what you guys think. I would like to think that if my fuel mishap was the cause, I would probably be having problems on other injectors as well.
