There are a variety of problems that could cause that, but if you mash the accelerator and it dies, you may want to put a fuel pressure gauge on the fuel rail to measure your fuel pressure. Assuming you have the V8 350 in it, that engine can require upwards of 30psi at the rail, and even a few pounds less can cause it to stall. You may have a dying fuel pump or clogged filter. That's where I would start, hopefully this helps!

SOURCE: 2001 chevy silverado won't start when warm

Possible weak spark from ignition coil or low fuel pressure due to weak pump. Try spraying carb clean into intake throttle body when problem is present. If vehicle will start and run with a little spray then fuel pump is failing.

SOURCE: idles to fast

When I crank my truck it runs wide open for a minute of so and then it starts to idle down. What causes this? It is a 1992 Chevy S10 v6 pickup. How can I fix this problem? I have no manuel on this vehicle for a diagram of the engine at all.

Thank you. Dave

SOURCE: surging and high idle on 94 silverado

If your idle is going from 500rpms to 1000rpm's fluctuating at and idle your EGR valve is probably carbon up and needs cleaned or replace.

SOURCE: 99 chevy silverado running rough and stalling.

the problem you are discribing would lead me to belive your fuel filter is clogged which is a simple fix 3 dollar part at any part store or on the worse hand your fuel pump itself could be weak you can open the gas tank cover and have another person turn the truck key to the on position without going far enough to start you will hear a faint whining noise if it is going bad or a louder noise if it is fine Good Luck

JUST REPLACED CARB ON MY 1992 CHEVY SILVERADO WITH A 4.3 LITER. NOW IT STARTS AND RUNS FINE UNTIL IT WARMS UP THEN DIES AND WONT START FOR 30 MIN


How many rpm's is it running at when you first start it up and it is running on the choke? Does it gradually start to idle back and then start to die r does it do it all of a sudden and dies?

When running with the choke on, it is on the high idle circuit of the carb, as it warms up the idle should slow down and then idle in the 800 rpm range in Park, 650 in Drive. This will be the low idle circuit range. This transition inside the carb will cover an idle air bleed hole in the venturi of the carb and lean out the mixture. If you notice that the carb smells gassy and black rich unburnt gases are coming from the tailpipe, the problem is located within the carb and requires a carb tech to do a rebuild of the carb. You could try a good carb cleaner like Lucas by putting it into the gas tank, in case you just got a bad tank of gas, but that is just a bandaid for a more deeply rooted problem. Get the carb rebuilt?

Service engine soon is on and the truck idles low when cranked.


Take the vehicle to an autoparts store and have them use a scan tool to retrieve the fault code(s) stored in the computer. Most stores offer this service at no charge. The codes will help identify the problem. Sounds like a faulty Idle Air Control (IAC) valve to me, but the codes will narrow the reason down. Hope this helped and best wishes.

1992 Chevy Silverado idles rough why?


Check your MAP and TP sensors. Your throttle body may be having trouble determining position and is compensating by adjusting RPMs.
