Okay so its a 95 blazer 4x4 4.3L vortec 6 runs great.... then check engine light comes on and revs to 2000 rpm?? its a 1995 so i figure its an obd 1 but it has a 16 pin connector ?? if i flash the ecm by pulling the fuse for ecm/batt check engine goes away runs fine until light comes on again! sounds like a egr valve to me? so i bought a haynes manual and it does not show the egr valve for my engine? ugh i am mechanicaly inclined but this thing has me at wits end!!!!!
please somone explain a little bit to me before i replace O2 sensors mass flow sensors !!! and a egr valve
