Just wanted to say this was all resolved by unplugging the battery for 24 hours then doing the relearn procedures. Can't say whether the replacement accelerator pedal/throttle bodies even helped, would recommend for anyone in future struggling with this issue to do this first.

Jeepers that looks a bit tedious, so it was removed and relocated to engine bay? Where did you put it?

Thanks for the reply, took it to 2 shops today including na auto electrician... No real info aside from it possibly being the pedal itself and some more data. Is this similar to what you had?

Probably noteworthy to also mention it only touched it for a moment but that was quite a while ago. I sourced some second hand throttle bodies and the issue continued.... I'm stumped at what it could be. Maybe the car lost its uprev tune or the low exhaust caused a crack in one of the extractors (as it does make a weird sound through the exhaust towards the front).

There was an incident whet I may or may not have charged the battery using another and accidentally threw positive on negative terminal. Sparked but nothing seemed damaged, in saying that I have grounding cables going to each throttle body. (removed them to see if this was the issue but to no avail)

Thanks for responding Sonicii, I was only using the CEL flashing method. Today I managed to get hands of a proper consult device and the following is returned along with videos of voltages/etc of when it occurs. Although I no longer have access to it I'm sure this should be enough info to figure it out. Codes: P0123 - TP SEN2/CIRC-B1 P0223 - TP SEN1/CIRC-B1 P0228 - TP SEN2/CIRC-B2 P2133 - TP SEN1/CIRC-B2 Videos of sensor data:

Hi folks, I'm wondering if anyone can shed some light on the issues I'm currently experiencing, personally I believe its one of my throttle bodies gone but maybe someone else has experienced something similar. Basically I just started my vehicle and drove home, noticed that at periodic moments it would rev up approximately 3,000rpm above what it was on even with foot off the accelerator pedal, braking stopped it revving. I got home and sat it Idle, at the 3k or just above it mark it will rev to 6k without me touching the accelerator along with a peculiar noise. For reference I've checked the MAF sensors/reset ECU/idle learning/etc/etc, the ECU is throwing absolutely zero codes at me although the light will come on occasionally when it happens. Any ideas? Thanks in advance for reading :)

Hey dude, sorry to hear of your issues. Have you installed test pipes? Mine was actually a failing throttle body from which I was able to install one from a 350z and do the relearn sequence. If you have the auto trans then uprev cant adjust the shift points or idle. They really should've only suggested uprev if you're running test pipes or some other mods.

See above

$1280 NZD all up $22.00 - O2 boss and bung for wideband $500.00 - Factory ECU reprogram to my specifications? $50.00 - fit o2 sensor boss/pre dyno checks $25.00 - Flash the car with uprev to confirm that it is flashing correctly $65.00 - Dyno Setup $390.00 - Full re-flash using uprev to suit mods (run itself) $65.00 - Dyno removal Add on 15% to the above prices for gst lol, as far as im aware I own the license and the license is locked to the ecu.

Unfortunately no AFR charts, I'll be sure to ask for them next time. To be honest I was expecting a bit more, but I failed to take into account the drive-train loss. Its definitely faster than it was before, noticeable throughout the range However she does use a bit more fuel in general cruising and I thought that since the cats were removed it wouldn't have to dump as much fuel to cool them down. The misfiring disappeared after I did a DIY grounding kit to each of the throttle bodies so I'm thinking one of the grounding wires is out to a throttle body and it was going out of sync at a specific throttle position.

Hey man just the following: 1. Stillen Gen 3 Long air intake 2. Megan Racing test pipes with custom dual exhaust Blitz mufflers and resonators. 3. Some 12v to 16v ignition coil thing that came with it from Japan

I'll upload a picture of the sheet when I get home but I think it came out around 276hp at the wheels, given it's an auto/sedan and the extra loss I think it came out alright. I probably could've changed the plugs and done a few other mods. Note: this was done on a dynapack

Hey Folks, Finally had this resolved..well partially. I decided to do a grounding kit but firstly one to the main block and 1 to each throttle body. I honestly can't even begin to explain what a difference this made, although in this case im unsure if it was just a bandage to the problem. Pro's -Smooth Shifts -Appears to shift at more appropriate times -Less accelerator delay I'm going to make to additional grounds to the trans/alternator/ecu/etc to see what kind of chances happen.
