Somebody please play Santa and give me the gift of insight that will make this truck happy. I have been 'round it, and through it, yet still the gremlin rules.

Tuesday the truck was, once again, the center of attention in the lab. The instructor took his trusty stethescope to assist in diagnosing what we all thought we heard..."an air whoosh at the intake somewhere." In the end he concluded that it may be the normal sounds you hear entering the throttle body. But in five years I've never noticed this before. I have changed the throttle body assembly but that noise was there with the old one as well.

He then began checking each plug wire in turn. Number one and two were not sparking each time. The first time he took them off there was nothing, the second time, he got zapped, the third time there was nothing again. We agreed that those cylinders may not be firing all the time. I have changed the coil, rotor, and wires. The cap and rotor were new as of June and the cap looked excellent so I didn't bother with that. The only thing left as far as electrical that would make it misfire would be the dizzy. I had heard a clicking noise coming from the dizzy last week so I thought "BINGO", problem solved right? Wrong.

Yesterday I switched out the dizzy with another and still no change. I drove the truck home and at first it seemed fine then it was right back to its old symptoms. Depress the pedal and the truck just won't go. Then suddenly you get a spot where you are able to accelerate but no "umph". I did notice that if I put it in "2" I am able to get a bit more "umph" a bit more quickly and with a lot less "deadness" in the pedal. It still feels as if it's lurching and I can still put it in neutral and rev it as if nothing is wrong. But once in gear it is sputtering. The idle is aweful...jumping all around most of the time.

I put it in reverse to back into my garage which has a slight incline and the truck did not want to go at all. I managed to get it in there but was shocked that I was nearly unable to use reverse.

K', whose gonna be Santa? I know someone's got the advice I need, we just haven't realized it yet.
