It sure sounds like a low charge condition, what are the system pressures on the low and high side ports.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 (1996 and newer) or a OBD1 (1995 and older) fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

Usually a problem with a dirty throttle body or a faulty idle air control valve. The computer controls idle speed by regulating how much air enters the intake thru the valve.

Google states: Hold the ateering shaft at the steering box with a wrench or channel locks, have someone get in and turn the wheel. If the wheel turns and the shaft doesn't, then your problem (or at least part of it) is in the shaft between the wheel and the box. If the wheel does not turn then hold the steering box output shaft and do the same thing. If the wheel turns and the arm does not then you have play in the box. This should be adjustable. If there is no play in the box then check the tie rods and ball joints.Td

It could be a fuel problem, the pickup coil in the bottom of the distributor, or the ignition module among other things.Someone would need to figure out if the ignition system is causing the problem or if one of the injectors is failing.

a bad distributor

take a truck diagnostic tool to check, the NEXIQ 125032 plus software can do.

Thats not enough information but, it sounds like it's starving for fuel. If you shut it off and restart it, does it fix it? Maybe a fuel filter. It's 8bux. Two clamps, and 5 minutes
