When's the last time you replaced the spark plug wires? Try that for you mis-fire. As for the vacuum hose, there should be a routing diagram somewhere on the hood or engine compartment somewhere. Trace it out and find where it should go. Oh BTW, bad spark plug wires can ruin a distributor cap.

Engine problem


Probably a head gasket problem,once again. It's burning the coolant off the plug . To make sure ,use a "block tester" from NAPA ,it is a liquid that changes color with the presence of exhaust gas in the coolant.

Check engine light


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.

Check engine light keeps coming on


The 1st thing to do is find out which one of over 100 codes is stored in the engine computers memory, whenever the check engine light comes on a code for that problem is stored in memory. You can go to any Auto-Zone parts store and they will run this code read test for free, then post them back here and I will help figure out what has gone wrong.

Is there a fuel filter on this car,if so,where.


this is a driveability issue chances are your computer control is trying to compensate for the problem. did you replace the fuel filter? if you have then it could be one of your sensors in the fuel circuit. either O2, IAC, or the TPS. has your check engine light come on? i would suggest trying a new fuel filter first. also make sure that the air filter is clean. a dirty filter will always make a car feel like it's low on power because a engine needs to breath. hope this helps you. please rate this solution. thanks
