Hello,
My 1995 Chevy Silverado 1500 4x4 v8 5.7L has been acting up for a while now. It is lacking power for sure, and it has a very, very low idle consistently, no matter what time or what temp. it is, and the idle is rough as well. It stalls when stopped(Like at a red light)Sometimes, and when parking(when foot is on brake coasting into a spot) but not in park. Also stalls in reverse, more often in reverse than slow speeds. I have replaced just about any part having to do with idle you can think of and more, including Throttle position sensor, PCV valve and hose, Idle Air Control Valve, Carb Hose, K&N Filter, MAP sensor, Temp Sender, new oil and filter, new battery, E3 spark plugs, fuel filter and the Oxygen sensor. and I have even ran a can of 44K through the tank, I have tried carb cleaner, and leak sealer, also transX treatment! I know the truck needs a new radiator and hoses, and she also has a squeaking noise coming from under the glove compartment in the cab, but I replaced the blower motor resistor and still makes noise. im stumped. Any ideas? vac leak? TCC maybe?? Any help would be greatly appreciated! This problem has gone on long enough, and I would take it in to be looked at but im a kid still in school and money is tight. Thanks!

sounds like fuel starvation.

What does fuel starvation refer to?

kevinkpk

It's not getting enough gas. Either low pressure from the pump, regulator, stuck injectors (however other than low fuel pressure it should have check engine light). This has a carb??

There is no check engine light, there hasn't been one since this started. No it is TBI fuel injected.

I'd suggest look at fuel pressure, probably a weak fuel pump

Ok, thanks for the insight! I"ll take a look!
