I bought my 03 350z about 4 months go, it has currently about 80k in it. My issue is the car jerks in almost every gear at 2000 to 3000 rpm. It got to the point to where some times on 5th gear it wouldn't pass 3000 rpm even after flooring the gas pedal. It doesn't do it all the time, but is doing it more often now than it was about a 2 weeks ago. I took the car to auto zone because I have the "Check Engine" light on. It came up with the following codes; P0011, P0340, P0021. Now, last Sunday I tried to start the car, I would turn the key and it acted as if the battery was dead, it would turn on all the lights in the dash board but it wouldn't start. this went on for about 2 to 3 minutes after several tries. Ever since Sunday, this has happened several different times including today. Has this ever happened to anyone else before?

 

What did google say about the codes?

 

check your ground at the battery, these symptoms you listed about starting the car happen to me when the ground is loose or is not grounded properly

 

P0340 (bank1) Camshaft position sensor, rear of motor on the passanger side

P0011 (Bank 1); P0021 (Bank 2)
- Intake valve timing control performance, There is a gap between angle of target and
phase-control angle degree.
Causes:
- Harness or connectors (Intake valve timing control solenoid valve circuit is open or shorted.)
- Intake valve timing control solenoid valve
- Crankshaft position sensor (POS)
- Camshaft position sensor (PHASE)
- Accumulation of debris to the signal pick-up portion of the camshaft

 

thanks, i will try.

 

if ground doesnt work get the sensor, i think like $70 and a common issue

 

Low oil level can also cause those codes together

 

Welcome to the forum. The forum has a wealth of information. Happy Z sorting.

 

You have the codes. Look them up and start your troubleshooting.

 

Hey guys just to let you know what I ended up doing. I replaced the bank 1 (passenger side) CMPS. I did the trick, but the funny thing is, i could not screw it back down. Every time I would tighten up the screw it would start to misfire or jerk again. So I left it without the screw and just placed the sensor back in the camshaft and I been driving it without it for about 2 weeks now without a jerking issue. I will eventually place the screw back to see if the jerking comes back and I'll be sure to post something up. Thanks for the suggestions.

 

^ thats weird but I'm happy you can at least drive your car now.

 

Check your grounds again, that's a strange issue to be having.
