Installed new O2, apparently the old one was not plugged in all the way.. I changed it anyway.. Went drive it and I had no clutch pedal, the master I installed was sticking.. swapped that and just drove it again.

I am stumped/annoyed. the O2 problem I saw is fixed but the loading up stumble and die is still there.. I don't see anything in the scan that could cause it..

It seems to be there slightly in Open loop, worse in closed loop ( to the point of the car dying.. not sure where to go next..

Strangest thing.. car is running like crap.. pull it on my lift shut it off. wait 10sec, start it.. runs/idles fine..

Now here is what I changed over the winter:
Plugs
Wires
Injectors
BIN in PROM
used a different plenum and IH but I don't think there is an issue there..

Things I am guessing it could be:
Ignition module?
Coil Packs?
BIN IN PROM
