Need help LT1 randomly stalls, then starts up fine? My buddies LT1 with H/C and also has obd1 and the knock sensor, randomly stalls then he has to wait a couple minutes and it starts back up fine and he could drive another 10 miles and it wont stall, but then he could drive 3 miles and it could stall 3 times. Any Crank or cam sensors that can cause this? opti has been changed 2 times, new tps, wires, coil, plugs. Just need some leads, Maf is good, no air leaks that he can tell?

Totally a shot in the dark, but you mentioned the knock sensor....... I disconnected mine. Might try the LT4 knock module (the little chip in the computer). They say the stock LT1 knock moduel will respond too much to mods, i.e. valvetrain mods. You could also have a fuel problem. You say "stalling," so is it more like waves or a miss? If it's what I'm thinking, it could be fuel so change your fuel filter and check your injectors.
