Own 1991 chevy pickup silverado. It starts and idles fine but when I put it in drive it moves forward a little bit then stalls, but when I put it in reverse and move backward it doesn't stall.

Sounds like some type of vacuum leak. I have seen either small vacuum hoses off the intake or an actual Intake Gasket leak... Best check out is a Smoke machine test hooked up to any vacuum hose.. if not available , spray areas of hoses / and around engine intake with some type of cheap spray Throttle Cleaner .. small bursts.. if you have a leak and it sucks in the vapor it will make the engine stall/die. That will give you general area to start looking ..

look for a vacuum pipe from intake manifold to gear box

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.

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

Before you do anything check the coolant level,not just the reservoir but the radiator(check it when the engine is cold!).

Make sure your transmission fluid is up to level, if it is, put a little bit on your fingers from the dipstick, does it smell burnt? if your unsure rub it between your fingers if it looks more black than red and feels gritty its burnt, try changing fluid and filter if that doesnt help your forward clutches are out, ive had some luck with trans-X in situations like this but its rare that it helps and almost never lasts hope i could help

first check the air and fuel filter. you could also have a clogged catalytic convertor. do you smell rotten eggs? if so it's bad. good luck

it could be a clogged convertor, or theres a potatoe in the tailpipe.
