Hello all,

I am a new G35S owner and I hate to admit it, I broke her already. I cleaned the throttle body based soley on YouTube videos. Some said to take it out, others said to never take it out. Some had no problems with manually moving the butterfly levers and others (such as myself) it caused major issues. I now have the above codes and an extremely erratic idle, bouncing between 1 and 2 when in Park and/or Neutral. I know its an easy fix that I am overlooking. A small sensor, bad timing on the relearns, etc. I am a rookie Infiniti Owner afterall. Any advise would be great based on the codes that are firing. If I can get her back to her top form again, all will be right with the world for me. Thanks ahead of time gentlemen and happy to be here and part of an elite group.

Hi and welcome!

What year is your G35? Thanks.

First thing I would attempt is an idle relearn procedure.

 

Hi Bob,
It's a 2007.

 

I have tried all of the relearn procedures several times daily since it happened with no luck.

 

Unplug the throttle harness and look for a bent pin, any oil contamination, or anything else obviously wrong.

If that doesn't do it then unplug the harness, clear codes, see what comes back.

Are you SURE those codes you listed are exactly the ones your scanner pulled. If so then you need to use a different scanner, one that has protocol 9141-2 because half those codes you listed are not even codes for the G35 so the scanner is misinterpreting the data because it doesn't have the correct OBD2 protocol.

I'm guessing you have a 2007 COUPE with the VQ35DE motor since you didn't use the plural "throttle bodies" and the 2007+ sedan has TWO throttle bodies. Just want to verify exactly which vehicle you have.

Did you work the butterfly plate by hand?

Which resets are you doing, you should be doing THROTTLE CLOSED RELEARN. Then getting the engine up to temp and following all the steps in the FSM to get the car in the correct state to perform the IDLE AIR RECALIBRATION.

If you accidentally typed in the wrong codes and you are actually throwing 2122/2123 then those codes are actually for the APP (gas pedal switch).

 

Thank you all for all of your help and support. I broke down and put her in the shop for some professional TLC. As it turns out, nothing would have worked because the entire computer needed updating and rebooting first and foremost. Then, diagnostics began. I hope to have her back today sometime but I want her taken care of most of all. That is what is important. Updates coming soon and thank you all again.

She is beautiful!
Hopefully the fix is a simple and not expensive one.
