OK so this is gonna be long and drawn out but whatever.

2003 Infiniti G35 couple 6mt VQ35DE

Last weekend had my clutch replaced, fly wheel resurfaced, and oil change. While the shop was working on the clutch they noticed the motor sounded off and the CEL came on. They pulled codes and got po340 (bank 1 cam sensor) so they replaced the sensor.
Picked the car up, replaced a head light ballast (driverside) and both head light bulbs. After that was done, i washed the car, let it sit for a bit then decided to take it out for a cruise. Maybe 2 miles into that drive, CEL, VDC off and SLIP all came on. once this happened the car would not go past 2200 rpm. So pulled the codes, p0340 again (bank 1 cam sensor) so brought it back thinking maybe its a dud part. tested the sensor, it was fine. and from there I have been throwing parts at the car hoping something works. So far have replaced bank 1 and 2 cam sensors, crank sensor, MAF sensor, cleaned throttle body and reset ECM. Lights arent coming on any longer but the car still stops at 2200 rpm. Almost like it's stuck in limp mode. As far as mods, upper plenum spacer, cold air, full exhaust, o2 sensors arent that old oh and short shifter.


Does anyone have anything that might help me out? I've old sunk 1700 bucks into the car at this point just this week and I'm on the verge of just turning it into a bon fire.

 

Sounds like your in "limp home" mode. I don't know if that can be reset with a common OBD2 tool.

make sure they lined up the flywheel right. They probably messed up and now you are footing the bill.

 

Why are you doing all of this - the shop messed up your ride beginning with that first code. Obviously somewhere in the removal and replacement of your flywheel they have screwed the pooch and now they are letting you think that it's just the car? BS! If the engine was running properly when you arrived at the shop, it should be when you leave the shop.

 

If they tested the crankshaft positioning sensor and it is ok, then the shop definatly didnt align your flywheel properly when reinstalling it. Your flywheel has a timing notch on it, if the shop didnt install it right, then it is same thing as the sensor going bad. The shop should have used a sharpie and made indexing marks on flywheel and crank, then easily realign when reinstalled.
