Check your MAP and TP sensors. Your throttle body may be having trouble determining position and is compensating by adjusting RPMs.

In the convinience center underneath the dash to the left of the steering column, against the firewall.
The horn relay is to the right of the turn signal flasher, and is a bit smaller in size.

this is going to sound kinda stupid but i had the same problem with my 88 earlier this winter . It could be as simple as water in your fuel. the solution would be to put HEET in the tank. I prefer the red can unless you have a diesel. I live in interior alaska and if you let your tank get below a half it will condensate inside. This sounds to simple to be true, but if you live in a cold climate it makes a big differance. Water will make it run like ****.

Here is a diagram. Arrow denotes rotation direction of engine.

takes two people, just like brakes

yea the blend door motor is bad it does not have a heater control valve

Under the black plastic panel on the firewall above the heater hoses under the hood there is a fuse and a relay for the fuel pump.

Is this a high mileage engine? Have you checked to see if a worn timing chain may have jumped a tooth? Sounds to me like it's out of time.

first check fuel pressure with a mechanical fuel gauge that attaches to fuel line schrader valve. around T.B.I. if no pressure with key on check fuel pump relay for correct operation, and also the oil pressure switch has the fuel circuit to it so possible oil pressure switch also. fuel pump has a check valve to keep fuel from going back to tank, so when u turn key on fuel pressure should go up within 1-2 seconds on gauge. if fuel pressure goes down quickly, possible bad fuel check valve, change fuel pump and fuel pump check valve (located right above fuel pump inside tank)

Hope this helps (remember to rate this answer).

engine shudder, knocking, pinging.

This misfire could be an intake valve or exhaust valve stuck open. Remove spark plug, and use a fiber optic camera to look in the chambers to look at the valves. It could be a bent valve or badly worn edge of a valve or simply a build up of carbon debris. I own a 95 Jimmy with a V6 Vortec and it has the same problem with a miss. mine is a bad valve, I hope yours is something small, but I hope it helps anyhow.

try looking on passenger side of front differential gears for a cylinoid , one large nut holds it in and should have a electrical plug. if this is bad your 4x4 will not engage . the bad news is it cost about 130.00 bucks but is easy to replace

If you mean just a spinning noise you'll need a new starter but clean the battery connections first with a steel brush. poor or loose connection cause the intermittent problem with click,click crank.

The coil is right beside the distributor cap (follow center wire on cap,goes to coil) and the module is inside the housing of the distributor cap(remove the cap with torx screws.)

module is under the distributor cap, bolted to the plate that the cap bolts to. It will have two wiring harness' attached to it. The coil is off to the side on the passenger side If I remember right and it too has two wiring harness' attached and one "spark plug" wire from it to the distributor cap.

The ignition module is bolted to the distributor, underneath the cap. It has two wiring harness' attached to it. The coil is mounted off to the side. I thnk it's on the passenger side. It too will have two wiring harness' attached and one large "spark plug" wire from it to the distributor cap.
