and all it took was 5 pages of updates and 45 days to do what you posted in Post #2! :mrgreen:

Im just glad to confirm it wasnt my incompetent tune that's caused this problem. Joe, I think this may be related/cause of the stalling/idling problem you tried to help me with in May 2012.

To...

Well, no better way to test if the rewiring of my bank1 O2 fixed the problem than a 2 hr 30 mile commute this morning.

Electrical problems are just weird I guess. Nothing I tested would repro...

The car is running rich according to my wb and bank1 injectors dump fuel when the O2 starts acting up which leads me to believe bank1 O2 is reading lean.

I probably should just run new signal...

I could. The easiest thing to do would probably be replacing the plug on the sensor to match the rear sensor harness plug. I tested bank1 sensor1 for continuity and they checked out fine. I checked...

Repinning front and back on bank 1 didnt seems to work. The connector and pins are different and using a Camaro front o2 sensor didnt seem to register for some reason2

I swapped and repinned...

The rear sensors are not in the car and the connectors are just hanging there. Im going to re-pin and swap connectors to see if that fixes the problem.

I think instead of trying to chase it, I may just re-pin my harness with Bank 1 Sensor 2. My rear sensors are tuned out so if there was some sort of short in Sensor 1 harness, maybe it is isolated to...

Finally got to check for continuity and it checked out good. I guess the next thing to check is the pcm.

Gotcha

When you say test for short to ground, are you suggesting wiggling the harness at the PCM or at the sensor or both? Also, would this be done while scanning with the engine off but the key in the ON...

So it should not be reading 450 +/-20 mV? You mentioned it's possibly a short to power so it's not a ground problem then? I guess the easiest thing for me to check is the PCM if I have one...

My VE table looks a bit off but nothing else looks weird to me.

Sure. Should I disable dtc's?

I have both banks set to 450 mv.

Attaching the log file from last night.

No STFT on this one but I'll add it to my pids and log that in the next day or two.

15622

Yeah. I can try to log some STFTs. May take me a few days to get to it since summer's been crazy. Would it help if I attached the previous logged file? Dont think this could be valve-train...

Ltft is disabled.

Clogged cat? Even if I have an x-pipe? That wouldn't cause the computer to adjust bank1 injectors, would it?

Have not tested in OL.

Hey Joe, Nothing changes when I swap injectors. I pulled my FAST36 injectors and replaced them with stock Z06 injectors (adjusted BIN) and the O2 still freaks out. I get...

Im out of ideas.

Ive swapped injectors. Swapped O2 sensors. Swapped O2 sensors between banks. Swapped battery. Can anyone give me an idea what is causing my bank 1 O2 to spaz out like this? It...

Joecar - Thanks a million. Wouldnt have made it this far without your help.

It makes so much more sense when someone is able to confirm the changes. Plus having my pid file fixed didnt hurt...

Just to update, Im on tune edit (6) and Im now slowly chipping away making small adjustments to the 6500+ cells of my MAF table. I think it is interesting to see how far off my MAD table was after I...

I know it's probably not necessary to keep posting up the logs and screenshots but I may as well keep doing it until my MAF is dialed in and I get a good usable reference for the VE table just in...

This was my drive home. It's a lot closer.

I made some manual adjustments to take some fuel out 6300+ and smooth the MAF table based on the previous WOT log.
