Good afternoon, ill try and give as much detail as i can on this and TIA for any advice!
A little info about the car -
2018 42k miles owned since 9k. No prior mods were done to the car except PPF
Stock tune
Stock motor
Roush CIA without tune (installed 2+ years ago)
2 12" subs connected to one amp (installed 1+) years ago
New battery back in June (Fully charged by Autozone and tested with positive results last week)
Okay so long story "Short ish" last year I had transmission issues (3-4 shift fork). The car got put in the air in the first week of june, attempted to do the tranny myself, said nevermind and found a shop to finish the work. Oil change was done in June. Shop had the car for 5 weeks, i picked the car back up and the transmission had issues within a day but was told the noises were normal. Drove it one more day before it got worse and then parked it. Returned the car to the shop the following saturday. Car drove like 50 miles total in that week as shop was kinda far from home. Shop took another 5 weeks to get the car done. I get it back and was having issues with the crank position sensor not wanting to do the relearn. (This was my fault as i took the sensor out in june due to an unrelated issue and installed it incorrectly.) Finally in october I got the Crank sensor in correctly and was able to do the relearn. I used an OEM sensor from ford as I was paranoid that it was a sensor issue, not me installing it incorrectly (I was wrong) but new OEM sensor is in. Crank relearn done. Car driving great...for 3 days. (transmission is fine this time, its unrelated to that). While driving the car over that weekend, i filled up from about half a tank to full with 91, then that sunday night I was down to 1/4 tank and 1 mile from home when the car starts misfiring and shaking. I get the car home and the next weekend i checked codes. All of the codes above are what I got. I attempted a crank relearn using forscan but the codes came back. Since then I have changed all the spark plugs, swapped coil 3 with coil 7 but the codes stayed on Bank 1, and I did have a friend come help try and verify timing but im not sure we knew what we were looking for.
I did use forscan to run a test looking at the camshaft angles and can upload that here if needed, but there was something that stood out to me.
Exhaust B Camshaft Desired Minus Actual Bank 1 - 48.56 roughly 10 seconds after startup and pretty much held there the entire minute i or so i was ruinning the car. Every other Cam is within 2-3 degrees at any given point in the test except for this one. Motorcraft Cam Position Sensor was replaced for that cam in December with no change to outcome.
We did suspect some sort of fuel issue at one point so I did buy a new OEM Port injector to go into Cylinder 2 and put the old cylinder 2 injector into cylinder 6 to see if anything changed, however the codes stayed the same. I did go buy another 5 gal of 91 gas from Chevron and a bottle of SeaFoam and poured those into the gas tank just incase, however im not 100% positive thats the problem and im not sure how long that would take to cycle out bad gas anyway. (any advice here would also be helpful)
Obviously the Cam being that far out is an issue. Im a pretty handy DIYer with a somewhat decent selection of tools and the patience/willingness to learn how to figure this out. What would be my next steps to try and confirm if my motor is actually out of time (no timing work has ever been done on this car). How would I be able to confirm if it is some sort of bad gas? Ive done a lot of reading about it potentially being a VVT Solenoid issue (hopefully not phasers) but im not sure how to confirm it either way without firing the parts cannon.
Once again, I appreciate any help as im just a guy looking to learn more and get his car fixed.
