03 350Z Won't accelerate but idles fine - HELP!
I bought a 03 350z 2 weeks ago the car has 162k miles, was driving well, strong and no codes on OBD.
Yesterday i was coming home when passing the train line the car lost acceleration.
The car is idling perfectly fine, just wouldn't let me accelerate at all.
VDC OFF light and SLIP came on
The car starts well but no response from the gas pedal if I put it in first gear it run with the normal acceleration of the car, the other gears come in normal.
The obd codes that are appearing are
P2122
P2127
P2138
I would like to know if someone has already gone through something similar or can help me to know what may be causing this.
This is my first Post if i miss some information necessary let me know..
Thank you !!

Forget Google; download the ec.pdf section of the service manual at https://nicoclub.com/archives/nissan...e-manuals.html.
In it you will find that all 3 codes relate to the accelerator pedal position sensor. P2122 means a low voltage from sensor 1, P2127 means a low voltage from sensor 2, and P2138 means both sensor 1 and 2 voltages are abnormal. Any of these codes will cause the ECU to go into fail-safe or limp mode, resulting in poor or no acceleration. It could be as simple as a loose connector.

I have the same problem. Car is a 2003. Had a rough Idle I couldn't get rid of. Replaced cam, crank, all O2 sensors, Plugs and 1 coil pack and pcv valve. None helped rough Idle. But once in a while I would hear a loud pop from the rear.
Then one day I drove somewhere fine, Although it doen't run right, and everything was fine. When I went to leave I had the slip and tcu light on. Car would only idle.. I'm at a loss.
Anybody know a good nissan tech in Fort Lauderdale??
Thanks

OK. I replaced all the crap the idiots(not you people) told me. Both cam sensors, crankshaft sensor, all 4 O2 sensors, Plugs, only 1 coil pack, now the throttle body and cleaned the MAF sensor. And did a smoke test for a Vacuum leak. Oh and the PCV valve..
Now the computer says everything is working except the TPS sensor, which I'm ordering..
IS THERE ANYTHING ELSE YOU CAN THINK OF BEFORE I DRIVE IT SLOWLY, IN FAIL SAFE MODE, INTO A POLE AND GET A SLIGHT BRUISE?

Sounds like my car, but I haven't started troubleshooting. My code was for a corrupted ECU
