2008 Ford Expedition HELP.
Hello all.
I have a 2008 Ford expedition that misfires and I am stuck on what to do next. Truck runs great when cold but when it warms up it starts to shake and badly misfire on idle and under light accelerations. If I give it a bit of rpm the misfire goes away and truck runs smooth again until I come to a stop or try to accelerate slowly then it again shakes violently and if in reverse it stalls out. No codes when hooked up to the scanner and no check engine light.
I changed all 8 plugs (Motorcraft) and all new coils. I also changed VCT solenoids on both banks and Camshaft timings sensors on both banks. Still truck runs the same when it warms up. When replacing the solenoids we inspected the timing chain, phaser and rails/guides and everything seemed good. The chain is not loose or skipped a tooth. Like I said everything seems ok. No noise from the phasers when running. Engine runs smooth when cold.
Sorry for the long post but this is driving me insane and any help/input would be greatly appreciated. Much thanks in advance.
