1986 GMC Vandura Cargo Van/ Work Truck

This is being sold as is.I have owned this piece for about 10 years and it was used to go to and from a Fleamarket about 50 miles round trip on the week ends, the rest of the time it sat.Runs and drives all the doors work and lock.It had a not start problem when it was hot, so I have changed everything in the ignition system and fuel system and finally the computer and that was the problem.Now after about three months the problem is starting again, only this time when you are driving at full operating temp after about 20 miles it feels like its starving for fuel.It will not stall I just put my foot in it and it gets past the stumebull.I have always been abull to prime it and it runs, also this does not happen all the time.It blows smoke when you first start it due to valve guides my guess.So at this point I am tired of it.It has well over 100,000 mile, I tried to put in 100,000 miles where it says miles and that did not work to well so note it has miles on it.
