I had taken it to them again and demanded a refund multiple times. They told me they would look into but I sent an email up to the Corporate consumer affairs to see what Corporate will offer to do now.
Just getting tired of this crap with the mistreatment at the Service Center. I didn't want to pay anymore than what I could afford so I picked up my car still dropping into limp mode. They said that the code coming up now is P0507. The code was cleared before I drove off but it went back into limp mode again.
I ordered a Reman. Throttle Body and looking for a new MAF in the mean time. I know I'm pissed at Nissan for selling me a car with multiple issues but I'm going to change my intake back to stock to see if that may help since I have a CAI. If it comes out to be a bad MAF because of my CAI then my apologies to Nissan but I've had the CAI since 2007. Cleaned the filter often and also have replaced it. Don't know why this is going on now.
P2127 Accelerator Pedal Position (APP) Sensor 2 Circuit Low Voltage
P2138 Accelerator Pedal Position (APP) Sensor 1-2 Correlation
I read that you checked with a multimeter the ECU side for continuity with the wires coming from the pedal sensor and that it read 0V. I believe you should take a close look at the wiring for frayed or torn wires leading from the sensor to the ECU. Should everything be OK, then the problem's likely to be in the sensor itself, and in that case I think you may need to replace the pedal assembly....
As for the P0507 code, that's Idle RPM higher than expected. The idle relearn should be able to fix it....
