Ok here is what happened. I power washed the bed of my truck last night and as I was walking by the drivers side front fender well I thought I would blast the crud off my front shock and spring. Had to drive to work last night and all was fine, but when I started the truck this morning it started missing hard like once or twice every 5 seconds. I shut it off and restarted the truck and it has not done it since???? Could I have got some moister in the ECM?
