Same deal on my 94 k1500. Just bought it a week ago. 4k miles on rebuild. Engine tranny transfer case redone. Everything but the little things. Ran like a champ for a week then it started surging untill it stalled out on idle, especially if lights+turnsignals on. Unplugged IAC ran good for a day then back to the issue. Changed that out, it ran about 20 miles fine then, back to the same idle behavior. Noticed the rattle in the catalytic, changed it to magnaflow. Felt better driving, when in idle, same problem. Checked fuel pressure and it found to be low. Changing out fuel pump today. I'll update you after its installed.. In the end hopefully having all the little things updated also will keep this beautifull heap going another 200k miles.

What is a iac and what is az

diver8718

what is iac or az?

iac= Idle air control valve.

I'm assuming that the guy was referring to autozone as az

I have a 95 k1500 I will turn the key on and wait couple seconds and i'll hear a click in the dash and the gauges will come on then it will start fine ? is there a relay or something that would cause that?
