UPDATE; today I pulled the computer (no signs of water) brought it into the house for 4 to 5 hours, pulled the distributor cap rotor wires and plugs all are dry so I put it all back togather and after the motor warmed up it started to miss under heavy load again like last night, What could be causing this I am stumped and need your advise plz thanks.

I would also check to see that your computer is not wet. I had the same problem and it turned out that there was a leak dripping right on the computer. It is under your passenger kick panel. I would first of all remove the neg. from the battery so that you can reset the computer. Leave it off for as long as you can because in cold weather it takes longer for the computer to reset. Hope this helps

I had taken the cpu out and brought it into the house for 4 to 5 hours while it was in the house I pulled it apart to see if there was any moisture in it and it was dry at one time there was a leak on it because there was traces of white metal corrision but it was dry today, I`m not ruling out that this might be the problem but I don`t think it is here any other help would be good.......

Even though you checked your distributor, you might want to apply some WD-40 or other moisture-displacement spray in there just to make sure. Your air flow meter may be wet or contaminated, or you might have an air leak between the AFM and the throttle body. Also check your air cleaner, which may be wet or clogged. This can also be caused by wet or faulty spark plug wires, vacuum leak, or even timing (the car wash might be coincidental).

Thanks GREG but now im realy lost, just lately I have seen guys take about a air flow meter, AFM I like to think I know a fair bit about the 22re`s I`m no stranger to a wrench, I have basicaly build my runner from nothing but I have no ida at all what a afm is, could someone post a pic with a arrow pointing to it, and there is a white dial thing on my throtle body and the hoses look to be going to a vcv any ida what this does as I have turned it both ways while the motor is running and there isn`t any change in rpm`s thank again.

I would have to agree that the wash timing was just coincidence but I would as well check over the spark and fuel systems care fully. As to the afm it is highly doubtful that the afm is causing the problem but if you are looking then just look at where your air filter is and it is the black cover that is right on top of the air filter. If you search this site enough you will find a picture on what it looks like and what it does.

I had very similar conditions when my TPS (throttle position sensor) was causing trouble...mind you, there was an engine code to tell me. I've heard that it will cause problems if it's dirty or adjusted wrong - I'd make sure your idle speed is set correctly, and then remove / clean / replace / adjust your TPS. This link may help with the specs:

Oh yeah...this may sound obvious, but my fuel filter was also pretty dirty and I replaced it at the same time...I don't know if it was that or the TPS or both, but it made a world of difference. Good luck.

Yeah, that's about where mine was idling too...never below 1100.

Idle adjustment is on the throttle body. Looking at it from the front of the truck, it's on top at the left hand side...just a large flat-head screw (the only one like it). Try it and you'll know it's the right one.

That sure sounds like the right one, although mine's not white, it's the same colour as the rest of the throttle body. I don't know what the deal is...my idle changes audibly with a 1/4 turn of the screw.

If you have a spare intake why not just swap throttle bodies, TPS and all...might fix both issues at the same time?
