Hell here goes, swapped out the 02 sen. The map and it still died. Tried another pcm and still died. So i thought, Let's check the injectors. Pulled the plenum and swapped them out. Later i learned to ohm check them, So i checked the old ones and 1 was 1.4 ohm's. Speck is 11 to 14. So that was it, also one checked out at 6.4. So between the 1 Bad and 1 low i figured i had it made. The i ohm'd the set i just put in and there was another low one 10.2 ohm's. So i yanked the set i just put in and heated up some atf in a pot on a burner to heat the oil to 220 degrees and rechecked them. None shorted out when hot and they all ohm'd at 11.7. SO i put them in and when i went to install the plenum i noticed the pcv hose bent in a 90 degree angle so bad it wasn't pulling the crankcase fumes good enough. (that would explane the oil film in the fresh air hose). I also checked the vac. side of the egr valve and it wasn't sealing. (making a vac leak there- no wonder my vac. reading was low) Any way i cheated for now and made a asbestos gasket to plug it off untill i can swap out the egr valve. It's starting good and running down the road fine, No cutting out like it did and no c.e.l. Thank's for your help and B chatting to ya

You know this sounds all to familiar. I am presently working on a 91 lumina with a 3.1 and was starting to pull my hair out as it was giving the same symptoms of dying out then not starting back up or starting and dying even when cold. It had spark, fuel pressure, and when I checked the fuel injector for pulse it showed there was one on the front injector. There are only 2 injectors that you can get to, one at the front of the engine and one at the back. When I checked the injector at the rear of the engine it fired up and ran fine except for the miss from having the injector unplugged. Well when I removed the noid light and plugged the injector back in the engine died. So I unplugged it again and the engine fired up and once again plugged it back in and the engine died again. When I ohmed that injector it was 3.6, way out of spec. First time in 40 years of messing around with engines that I have seen 1 injector keep the engine from running. Never stop learning in this trade.
