I have a 2006 Dodge ram 4.7 liter 4x4, check engine light is on, code says #1 misfire and random misfires throughout. Severely blows white smoke, dies down after warm up. I have changed plugs, checked coil packs, compression test, did a leakage test on cooling system, (no leakage noted) ran the truck without radiator cap installed to see if head gasket was blown, no indication of that. What is going on? This seems to have started after I filled up at a BP station, thought maybe water in the fuel so I added 2 bottles of alcohol, no change. the truck has 119000 miles on it. PCV valve? Thanks.
