94 jimmy stalls

ok, 94 jimmy, 4.3 vortec,

had a no start last week, but since then it’s been ok.

stalled a couple times yesterday.

replaced missing grommet on left side valve cover and reconnected hose to it.

fuel pump is working fine.

get no trouble codes…

gonna pull the egr again and see if it’s sticky at all…

anything else i should look at?
