Bank 1 = Lean, Bank 2 = Rich
#16
Sure, I will look into the IAT wiring today. The flash should be for the manual transmission car.
Another thing I noticed today was that the timing advance shown by torque app ranged between -2 deg to 76 deg. Does that sound right?
6th gear at low rpm caused quite a bit of rattling sound. At RPM over 3-4k there wasn't any ratting sound.

I checked the timing advance again- it varies from 15 to 43 deg.
My MAF wiring is good so I replaced the MAF and the p0113 code is gone. Now I have a random misfire code and the car is still lean on one side and rich on the other.
I plan to change the passenger side fuel pressure regulator / damper next.

What exactly was the electrical issue? I'm seeing a very similar issue on my '07 G35 sedan. Bank 2 shows rich, bank 1 shows normal.

Always treat bank1 and bank2 and basically two different engines. The computer draws a hard line between the two, they have their own separate and complete systems.
Start with the spark plugs, that will tell you 90% of what's going on, does each plug look LITERALLY IDENTICAL?? Or does one plug look a little different? If it's different it could be just airflow and needing new plugs, could be a stuck or clogged injector, could be many things.
If all the plugs on one bank look LITERALLY IDENTICAL, then compare them to the other bank, if they look a different color it could be an upstream O2 sensor getting lazy and sending the wrong fuel calculation to the ECM, etc.

[QUOTE=RohitG35Driver;7127313]This turned out to be an electrical issue. We hired a specialist to look at the wiring and he seems to have figured it out. I really appreciate all your help in diagnosing the issue. The car now runs excellent![/QUOTE
Hey what's up I'm going through this issue at the moment. What did it end up being? Bad wiring somewhere? Or?

Had some time to look at my car. I had to stop panicking and take a step back. A quick look around had shown the fuel injector harness was pretty bad looking around were the harness terminates to the connector. This was causing two cylinder (3 & 5) to not fire at all. So check wiring for the fuel injector and for spark.

I’ve been having similar problems for a couple years now. Had my engine replaced and the problem’s returned...no one seems to be able to pinpoint the upstream cause.
thanks in advance
