Sometimes a picture is worth a thousand words. You should be able to find what you are looking for amongst these.

Wow...Try the EGR valve...Plugged catalytic converter

needs a tune-up, spark plugs, wires , distributor cap & rotor, fuel filter, air filter, might need coil also, put some drygas in fuel tank, check all vacumn lines, change oil & filter. DO ALL THIS , IT NEEDS IT i'M SURE, THEN YOU'LL BE GOOD TO GOOOOOOO!!!!!!!!!!!!!!!

if it was running fine before you changed the cap and rotor just make sure you put the spark plug wires back in the same spot you might have got them mixed up

4.3 enginges have a notorious ploblem with the distributor failing exspecially when engine is warm. If this car has the optical distributor the optics inside fail.

Here is the firing order for that vehicle and engine.

I would ask the Chevy dealer service dept. They can probably tell you.
