same exact thing happens with mine. i dont know what a egr valve is (Exhaust Gas Recirculation?)but mine seems to stall more when start my car in the morning and have to turn either the ac or heat on. i was thinking i was not getting enough power with all of the stuff i had running (like a alternator problem). i bought the extended service on my 95 so im still covered. maybe i should take it in and find out for shure.
