well, i need help. today i started my 07 g35. engine made a cough sound and revved up a little bit all by itself then rpms dropped to about 1 and when i completely press on the throttle the highest the rpms go is to about 1.2. then engine doesnt wanna rev. at first i thought it was the mass air flow sensor but its not. i got my obd2 scanner and heres the codes i got: p0223 p0123 p0122 p2135 p2101 p1078

 

sorry I can't help but are you in the UK with a 07 G35 sedan?

 

Any modifications? Nearly all of these are throttle position sensor related.

 

no mods, cars all stock, im in california. any way to fix. today the car wont even idle., starts n dies

 

Sound like it is time to have it towed in if under warranty.

 

no warranty

 

alright, again today same problem, i replaced maf sensors, no use, gonna go return them. i tried clearing the codes once more but cant seem to clear 2 of them for the throttle position sensor. how the heck do i replace the throttle position sensor.

 

problem solved, went digging around. the sensor on throttle body was loose, car started, but throttle was was funky, looked at codes, gave me maf sensor code, replaced with the maf sensor i bought, works. now another problem, power steering is jerky and makes a chewbacca sound when i turn the wheel

 

07' and no warranty?
