yes it misses. I started it today, runs ok but while it was cold it was not spitting oil thru crankcase! once it warmed up thats when it started spitting oil thru crank case. the gauge on the truck works but I dont trust it much! Im guesa t idle its 12psi and full throttle it gets up to 30-35 I guess. it smokes white smoke, at idle not much but at gull throttle it smokes a lot. it gave me a code for injector #8 too!
