Re: Finally drove the Z.. But have issues>>
Yea on the Q-driver....pulled that one from you know where.
If you think it's the O2, switch'em & see if it follows...if not then I gotta suspect an injector(s) maybe. My thinking is that ya have to mechanically verify what each O2 is telling you about the results of combustion in that bank, pull the plugs & or stand behing the car & sniff the exhaust when it acts out....gotta pass the smell test. JMHO.

So, it can happen that way. However, a loose or intermittent O2 connection might give you the same test results. Swapping the sensors** to see if the problem tracks seems like a good approach. **Would it make sense to build a wire harness that would allow you to simply cross-connect the O2 (connect the left O2 to the right ECM harness, etc) and avoid having to acutally swap them??

I'd be more concerned over the issues that could cause more than the inconvenience of swapping them. |

Re: Finally drove the Z.. But have issues>>
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

Re: Finally drove the Z.. But have issues>>
WTF.
We need to register with a real working phone # with matching address before we allow anyone to post,this way we know where he lives and can pay him a visit. Jeff, i would try the prom first,then move to coils. If it's ignition $$$$$$ module i would figure out a way to use LS1 coils. Pete

I swapped the PROM last night, I goign to use the OEM AYBK that I have. I ordered coil pack too, I figure I will pull the plenum tonight or tomorrow to swap them (should have them this week) and see what that does. after reading RogerZr1's post, mine issue sounds the same, bbut my car dies, makes me think it might be coils
