Question about 1991 Chevrolet K1500
I have a cherolet 1500 v6 and sometimes when I am in reverse it will stall and I will have to restart it and I have no idea what the problem is. Please help!!!
I know this is frustrating but I do not want you to throw money at your truck when it is not necessary. The 91 is an OBD1 system. Have you downloaded the codes? I can be of more assistance if I have the codes to diagnois. You definetly have a problem, I wan to solve it.
Since you just had a new engine installed and then the problem started, I would look very closely at the fuel lines. Perhaps the engine torque is pinching a flex line. Perhaps when you engage reverse, something is hitting and grounding out. It seems to me when you engage reverse the torque rolls the engine to far and maybe grounds out the coil. Are your motor mounts in good shape? Check by opening the hood, put your foot on the brake hard, engage reverse, and keeping your foot hard on the brake, give it gas. If the engine rolls up off the mount the mount is broken. You may need to have someone help you with this.
Let's keep talking. I really want to help.

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
