I have a 1994 Silverado pick up, 2 wheel drive manual transmission, 350 engine. I have been having trouble with it wanting to start. By this I can get in it of a morning and turn it over and normally it starts right up. After the warm up cycle it feathers down the idle and holds and runs normal. After that it eithrer just dies or after you turn it off it fails to start. If you dribble a small amout of fuel in the TBI it fires right off and as long as I keep the idle up it runs but let ir return to a normal idle it dies and won't start again. Back to an idle and it dies again. I have checked the fuel pressure and have 8 pounds at the TBI. I have changed the fuel filter and replaced the coil. Can it be the throttle position sensor or the MAP sensor? All wires to the computer have been checked for a break but none found. Thank you for your time.
