I have a 2011 G37 S. My car was vandalized and had not moved for a few months. Once I got the money together to fix the damages, I got her back on the road. Well I allowed someone to drive who drove it too hard. Now there are a load of issues. We started with a simple check engine light. It just started with jerking at 20 mph & 40 mph. This intensified to include 10 mph and 30 mph sometimes. Clearing the codes out had the car driving perfect. Now, the car jerks, tops off at 40 and wont pick back up until the speed drops to 35 and honestly sounds like its not shifting (the RPM steady's at 3).NOW on top of the check engine light the traction control light remains on (not the one advising it is on or off when you push the button).

We have checked all of the spark plugs. We have replaced the Bank 1 camshaft sensor, Airflow sensor, and engine variable timing solenoid.

When connected to the code reader it gives off different codes. All Bank 1. Camshaft sensor, MAF sensor pop up... even with the new replacements.

I am at a loss. Does anyone know what this may be?

If you did not use Infiniti OEM replacement parts and used cheap knockoffs you may have complicated your issues?

 

What was vandalized/fixed? Sounds like those could be unrelated. Sensors may be good so replacing them, while sometimes a good troubleshooting step, may not be helpful. Post the codes you're seeing.

 

The vandalism was unrelated. It was just damage to the body and windows.. very expensive damage I just feel like the way my "friend" drove the car after it had not been moved in months may have caused a couple issues to arise. I have only replaced the parts that the check engine light codes have suggested. I just went out and pulled the codes again and they are P0340, P0011, and P0223. I spoke a man at the store which I have bought all of the parts and he advised me that the Camshaft I purchased was under warranty and I could exchange it to see if it may fix the issue.

 

Be nice to know how many miles are on the car. If the car has lower miles, throwing parts at it is never a good idea, especially if aftermarket/non-OEM.

Vandalism may very well be related to your issues, did the car spend time in a body shop? If all of the "Bank 1" sensors are faulting, did the body shop work on that side of the car? Could a harness ground have been loosened, or the harness damaged on that side during body work?

 

The "store" is an Infiniti dealer, right?
If you are installing aftermarket (basically anything not made by the vendors who originally supplied Nissan, and ESPECIALLY Chicommie parts) on your car, expect to continue to have issues in the future!

 

You drove a car that sat for a while. It will be fine after a few exhaust emission cycles
