I currently have a Gryphon and am running the 87 performance tune.

Ok so earlier this week I started hearing wat sounded like a little rattling noise at certain RPM's. I assumed a loose exhaust clamp or something simple I could do when I had the weekend off. Truck has also been hard to start. I assumed maybe needed a new battery even though mine is only 2 years old


Today I was running low on gas and pumped in some 91 octane, only about 5 gallons. Drove home and idle at lights seemed a little rough. Picked up my daughter and headed home. Get home and stop just outside the garage to let my daughter out. Start to pull into the garage and engine starts running REALLY rough. Bouncing between 3-500 RPM's, low based on what I have seen.

Pull the code and I get:
P0012 Intake Camshaft
Position timing
over retarded (bank 1)

Code looked exactly as posted above.

Tune issue? octane issue? Other issue? Any help would be greatly appreciated. I am heading to the snow this weekend and do not want to get stuck up there...

Thanks.
