Maf. It could be the dizzy but didnt you just put a new one in (I maybe thinking of another member)

My money is on the drivers master control (mirrors, windows switchs) I just had the same problem yesterday with a non-nissan truck but it was my passager side window that wouldnt close. It went down fine but ouldnt go up.

Problem 1. I noticed that these truck dont shift at lower rpm unless you feather the throttle. Spirited driveing to me means more then 3/4 throttle and at that it'll shift at around 5,ooo. Although from what you say I think you mean it wont shift, it'll just stay steady at one rpm (like staying in 3rd unless you let off the gas) Problem 2. How has the maintance been on the tranny? It maybe time to change the fluid, filter and ad a after market tranny cooler. Genrally when reverse goes out it goes out without warning. it seems like it could be a line pressure problem though I cant say with 100 percent sertenty.

wd21's won in both '87 and '90.

If its loose and wont tighten go buy a new clamp. the clamps do rot after a time, take a hack saw blade and saw the clamps to see if theres any good metal left in them.

Is it puffing oil smoke at start up? If so you need new valve guides. If not look elseware for your problems. Plus I've never, ever seen bad valve guides cause a rough idle. And doing a 3 point vavle grind is doable if you've seen it done before. Even though you can do it with a dremel doesnt always mean you should. It would be best to take it someplace and have them charge you 2 bucks a valve to do it.

Could be the cap or pump. I dought its the cap because that should not affect the coolant getting to the heater core, Getting back from the over flow bottle maybe but not the core. Start with whats cheapest and work your way up untilyou find out what the problems is. Or yeah, did you purge the block? they could be air build up in it causing the problem.

I cant say for the new style apts but the older style is a very good trail tire. They seem to chunk a little more on rocks though but they last a long time on the pavement. Good buy right there.

Scrapes 170+ a ton. they would get 350 just for hauling it. Used cars are going up in price even those that dont run.

Does the exhaust smell nasty as hell? I say MAF senser is taking a crap, try wiggling the wires and see if it gets better.

The Grabber is a 7 ply desert race tire. Meant to take a lot of abuse, but they weigh a ton. Grabber AT2's are a all-terrain tire meant for street usage. HTS's are street tires.

A 4inch trailmaster is the biggest lift you can get for these trucks stock. But they havent been made in years so you have to find one used. A t-bar crank with 3inch body lift will clear 33x12.5s without a problem though and with trimming it will clear 35s. Although at that point the tie rods and centerlink are the weak points. A N/A rebuilt 3.0 should be around stock 3.3n/a (say 180hp, 210-20 lbs)power with the Jim Wolf Cams, custom ecu and headers. Maybe a little more if it needs to be bored out. But that would be a very minimal gain.

I ran 5w-20 once, it ate 2 quirts in 1000 miles. But I never needed a block heater or any of that nonsense with 5w-30 ethier.

Cut the bad stuff out and reweld it, its not hard at all. Most race cars have tubs were the rear frames are cut and re-welded. If you cant weld, find a old timer/ semi retired welder that used to work on buildings or pipelines. If you cant find one of those, take it too a dude (or dudet) that runs shop out of there garage. If you cant find one of those, then junk it, since you will spend more having a auto body shop repair it then buying a rust free one would cost.

Stock gears should be 4.36 or 4.62 in your truck. For t-cases it depends on the applacation. If your going to use a chevy tranny then you might as well use a chevy front axle (cheapest, parts truck swap) then I'd advise a chevy np241 with the shifter. If your going too run a ford,dodge or stock nissan front parts you could run a dodge version of the same t-case or a np205. As far as a 3.0 vs 3.3 vs 4.3 swaps. The 3.0 is the cheapest, followed by the 3.3 swap then the 4.3. A 3.0 or 3.3 with the stock 5 speed and a 3.92:1 t-case gear set would crawl pretty good in 4low and would be easier to complete. But the 4.3 offers more power (yah the 3.3 sc makes power) then the 3.0 and build tourqe at a lower rpm. For 35-37 inch tires you will need too do a SAS (plus no buddy makes a 6 inch lift for these trucks) The rear axle is good enough stock for this range of tires, although ifyou start making decent power (above 300lbs) or you stuff the rear into cracks you may want to switch to a 9 inch or dana 60 rear. Gearing should be around 4.88-5.13 with the 4.3/ 33s/c and 5.13 minimum with the 3.0. A dana 44 minimum for the front axle, a 60 is really heavy and over kill for your app. But the first thing you should do is put the 3inch body lift on it and buy a used set of 33s. Just to see if you want too deal with a lifted truck day to day. And decode your axle gearing, on the passanger side of the engine compartent there should be a tag on the fender, it will ethier have HG43 or HG46 for the code, HG43 is 4.36 and HG46 is 4.63.

4.3, there beat to death in fork lifts and pumps and they out last the toyota and nissan motors. But then you gotta change the tranny to gm.

Did you try putting another wire or plug on that cylinder yet? Since you have it narrowed down.

You did check your fuel pressure right?

My Fridays screwed up now. I guess I could find something else too do.

Try swapping a plug wire with the wire from the coil to the dizzy. As far as the likly hood, its a 25 year old truck. Stuff gets tired

I had a 76 k20 with a 14 bolt rear, uncles 4x2 79 f250 has a 60 rear. Depends on the Leaf spring packs only... And yeah, they can flex just as much as coils. 1/2 ton 88-98 springs would work nice in the rear, thats a basic toyota up grade for more lift. And the fact that its a lifted truck with solids means its gonna ride hard.

yeah, but only of it stock. There on the members page and in a few threads. I'm on Dial up so its a hassles to up load pics since facebook up-graded and photo bucket has never worked for me.
