chug/buck on decceleration
Dad has a 96 7.3, 5spd. Having a problem that I cant figure out (Im a chevy guy so the HEUI system is foreign to me).
Anyway, problem typically happens when hes deccelerating for a redlight. One place almost always does it because you are running 50-60 and this is the first redlight you come to. Come off the gas, and as you coast down with it in gear it will start chugging/bucking like its about to die. You have to push in the clutch and rev it up a bit and its fine. Some days it wont do it at all. Others once or twice, and some days its almost every redlight making you want to turn around and go home.
Also it seems to take forever to crank once its hot. I changed the oil (twice actually) so its rockin new rotella, has a new fuel filter, changed the cam position sensor, what now? Like I said, I am lost with the 7.3 injection system. Truck has <100k on it, so give me some ideas.
