I have two major issues with my truck, (1)I recently had a great deal of work done=complete tune up spark plugs, spark plug wires, distributor cap, rotor, changed all 8 fuel injectors replaced intake gasket, and water pump, truck still has a misfire, had it put on a diagnostic machine, they told me I now needed to replace the fuel injection wiring harness.(2) white smoke occasionally comes out of tail pipe, mainly 1st thing in the morning after a while it clears up, but even after I shut engine off, smoke still comes out of tail pipe as if its on fire or something. Is it worth repairing or should I start saving for another vehicle. One other thing it still responds very well when I get down on the gas pedal?

If the injectors were replaced, then try to find the offending injector and repair the connection as that is probably where the problem is. As far as the white smoke goes if it is only doing it occasionally then don't be to concerned about it. You have a lot of miles on and as long as all the fluids are ok you should be as well.
