92 210 Blazer W engine

Stalling when warm....when starting back up you need to put foot on gas and crank (hard starting). New cpi just put in. HELP!!!!!!!!!!!!!!

Many things it could be on the old Vortec, but start with pulling the egr valve off and cleaning the seat and pintle. This is the round thing on the front of the engine just below the upper radiator hose. Two 10mm head bolts to remove it.

Thanks we will check this out!!!!!!!

Yip, sounds like EGR.
