Were you ever able to get any codes out of the computer? Results of your fuel pressure test? At times when it is about to stall, does anything change if you shift into N to disconnect engine and...

Do you trust his diagnosis?

I personally am not fond of people simply removing the cats. It is technically illegal (though in communities where they don't do emissions testing, it is unlikely you...

What codes are coming up?

My understanding is that, when you disable the EVO system, the power steering system essentially reverts to a "traditional" power steering system. If everything else is otherwise working as you...

One somewhat common issue I've seen mentioned is problems with the EVO valve in the steering system. This variable valve makes the steering speed sensitive, so that it isn't as responsive at high...

Moved to Powertrain. It does sound like a pinion bearing, but certainly double check other things.

The pressure drops off after the pump shuts off. When you try starting the engine, the pump should start running and the pressure should come back up. Does it? There's a test lead (red, IIRC) coming...

So it seems pretty sure that you have the full time 4wd NP 203 transfer case.

Way back when I can recall helping my dad take our '75 203 apart to install the part time conversion kit. The 203 is...

I could be wrong, but I thought there were basically 2 different transfer cases used in that time frame - NP 203 Full time 4wd or the NP205 part time 4wd. What are your shifter positions? traditional...

I'm reasonably sure (my Suburban is out and about right now) that the unattached fitting is for an optional engine oil cooler. Replacement radiators tend to have both engine and transmission oil...

Why do you believe the MAF is at fault here? How are you determining that MAF is bad?

If you are getting codes for the MAF, remember that codes point to problems in circuits, of which the sensor...

Any good manual should describe a fuel pressure test. Basically:

1) before starting the engine you are looking for a pressure of 60-66 psi
2) A slight drop after starting the engine, but it...

If it's just about "spinning both wheels" here's how I see it:
An open diff will sometimes spin both wheels.
A limited slip will spin both wheels more often than an open, but will still sometimes...

I was going to suggest a fuel delivery issue. If you don't want to "guess and check" on the fuel pump, borrow the fuel pressure tester kit (I think Autozone lends it out) and see what the fuel system...

I have heard good things about the Detroit Truetrac, though I have no personaly experience. Technically, I would not call it a locker -- it is a gear type limited slip. A lot of people prefer the...

I don't know that there is a single recommended method or hardware to add a locker after the fact.

Cheapest, especially if you can sell your current axle for about the same as a junkyard axle, is...

This question gets asked a lot. It seems that most OBS trucks get away with 285/75/16 aka 33x11.50's. A good percentage of these need some minor fender trimming or tolerate minor rubbing (individual...

A repair manual will explain how, but you go in through the backing plate and retract the adjuster screw. This will draw the shoes in and release the tension on the drum. It is tedious, so it will...

I know different cars are designed differently. Ford and GM's have a "Schrader valve" (looks like a tire stem) in the fuel supply line/on the fuel rail that is intended specifically for testing fuel...

I would probably start by jacking up the rear and having a quick look. The few catastrophic diff failures I've seen have usually punched a hole in the cover which becomes pretty obvious once you are...

On my stock height '98, I put a set of 32x11.50R15 that I think look pretty good on her. If you have a little bit of lift, I would expect you could easily go 33x12.50R15.

AC's94chevy:

Assuming you have got your parts interchange research done correctly (including verifying that the recipient and donor axles have the same size/spline axleshafts), then it should be...

That doesn't sound right to me. When I have had a diff open (oil drained obviously), the R&P has always rotated freely.

I have never rebuilt a differential or set up gears, so I'm mostly talking...

I'm going to jump on tbplus and chromesilver's bandwagon -- never had a car payment and, if I have any say in it, never will. Buying older used, I paid ~$7000 cash out the door for my burban 4 or 5...

Assuming the pressure gauge is accurate, it seems pretty certain that the fuel pressure is too low. As you suggest, the next step is to determine if the pump is weak or if the regulator is opening...
