SOURCE: Smoke problem

hey
there are couple of smoke type.blue smoke is oil, black smoke is fuel, and white smoke is water, if it clears after starting and running a few minutes it's probably your valve guide seals leaking oil down on top of your pistons, causing it to smoke until burned off and foul your plugs.

A multi misfire may mean that one or more of the following has happened:
Faulty spark plug or wires, Faulty coil (pack), Faulty oxygen sensor(s), Faulty fuel injector(s), Stuck/blocked EGR valve / passages, Faulty camshaft position sensor, Defective computer.

The engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wire, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the the problems were faulty fuel injectors. 

Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.

Good luck and hope this information helps, keep me posted, be glad to help you get the truck running 100% again. Not sure if your running a K&N air filter, and if you are there may be a flim of oil on the MAF sensor that is making you run lean. You may want to spray down the MAF sensor with a can of MAF cleaner.

It might be an injector problem.Sometimes if the injectors are not sealing properly they can leak fuel into the manifold even when the engine is off as there is still residual pressure there and you engine would be essentially' flooded' when you try start it again .After half an hour or so,and it would take some seconds after that to run normally untill the excess fuel is burned.

Have them checked and replaced if needed.

Please leave positive feedback if I have helped

Thanks
