My 2002, 2002 freightliner 60 series detroit, Nothing for
Nothing for the only problem it has right now which is it wont restart when its warmed up. 1st thing ice cold it starts fine a7 will restart again and again. After its warm if you turn it off to refuel it will not restart for 30 to 45 mins. But it all started a couple of days ago. About 5:00 pm I was finally fully loaded with cars and started heading out of Ocooe FL for Columbia SC when I hit the Interstate the engine wouldn't rev but to about 1300 rpm's and then die but not shut off it kept firing back up as soon as the rpm's dropped below 1300. It ran normal as long as the rpm's were under 1300. So after stopping to see if there was any thing I could see wrong and I didn"t , I drove from Ocoee FL to about the SC state line at 54 mph when it started to improve a little. By the time I got to Columbia it would run 65 mph a while then start to die and come back below 1300 rpm then get better again. At Columbia I refueled and added a gallon of lucus fuel treatment, and notice air bubbles raising from the bottom of both fuel tanks. when I tried to restart the engine it would not start for about 30 mins. it spun over real good just didn't start up. When it did start I never shut it off til I finished my run delivering cars and got home . After the refuel I slept with engine idling and it has never run better since. But now ever time I shut it off warmed up or even just after running 5 or 10 mins. it will not restart for about 30 mins. or so. … read more
