My fiancé's stepmom called and wanted me to put my scanner on my fiancé's dad's nephews 2012 Ford Expedition which started running really bad yesterday and turned on the CEL. Truck has the 5.4L on it with almost 157,000 miles on it.
Pulled codes and the relative ones to the issue were some cam sensor codes on bank 2 and misfires in cylinders 5,6,7 & 8. I started the truck and it ran horribly. You could tell it was misfiring and not long after the CEL started blinking indicating a hard misfire. It actually died a couple of times while at idle. I did a power balance test with the scanner and the cylinders that I mentioned before were all staying in the low position of the test and not moving.
Prior to me coming over, they had taken the truck to O'Reilly's to have the codes read and they ended up buying and replacing the cam sensor on bank 2 which of course didn't fix it and is why they called me. I told them it looked like they had a timing issue and that the phaser on that bank probably malfunctioned or the chain jumped a tooth or so. Timing issues are common on this engine once they get some miles on them. I didn't have any more time to do any more checking.
Does anyone else think that this is a timing issue?
I was intention to clear the basement and I found silicon spray, liqui molly mos2 additive and can of ballistol spray- multipurpose. So I decide to use them, winter is coming, so I put in the Corollas engine 125 gr additive mos2 no need just not to stay at the basement. Than I spray all the rubber parts at the doors with silicon spray and the metal ones with ballistol. I clean up the basement finally
