There were three different engines for that vehicle in 1996, here are diagrams of the 3.9 liter V-6 engine, and the 5.2 and the 5.9 liter V-8 engines both have the same firing order.

3.9 liter V-6 liter engine;





5.2 liter/5.9 liter engines;

pick up a chilton book from chapters indago and check the diagrams they might be similar but i believe the wiring is a lot different '
it is likely you will need both manules

Firing order is:
on the stock intake manifold. It is 1,8,4,3,6,5,7,2 (i.e. 18436572, 1-8-4-3-6-5-7-2 at 4 degrees before top dead center). 1,3,5,7 is on the left bank ,4,6,8 is on the right bank. Clockwise distributor rotation. #1 is identified on the distributor cap, the wire clockwise is #8, etc.
1992 Chevrolet C 1500 P/U 2WD
5.7 liter V-8 VIN "K"

it may not be a vacumn leak from a line,check the throttle shaft for movement,for example,i had a 89 1 ton 350 and my throttle shaft was moving around a lot and in order to keep it from idling high,i had to kick the throttle pedal.But also check the idle air control valve,which is the round sensor on the side of the throttle body.

Hope this helps.
