Re: '93 Jimmy Vortec 4.3 stalls at idle under load
Welp, my thought is that you have low fuel pressure while at idle. This can be from a failing battery and/or alternator, a failing fuel pump, or even simply corroded terminals. If the fuel pump isn't able to keep up for one reason or the other, then the engine will die from fuel starvation. Another thing to look at is the fuel pressure regulator. This can cause hard starting and, in severe cases, stalling. This should be a good start...good luck!
