do you mean with the seafoam or afterwards? I ran the seafoam, turned the truck off for about 15 min, turned it on and let it idle for a couple minutes and then went for a 10 min drive. came home. truck sat for about 20 min to let the engine cool a little, turned it on to pull in the garage ran fine, did the plugs, runs like crap at idle....
