I have a 2005 G35 auto. 270k miles. Oil change done around 1100 miles ago. My car is tuned and I was revving it with the flame map on several times to cause pops and flames. On the way back home, I noticed the car was struggling. As I arrived home the car died on me. I let it rest for a couple hours and took it for a test drive to see if the problem was still ocurring. As I turned it on the car was rumbling and the RPMs were fluctuating. Not even a mile down the road, the RPMs kept fluctuating until it died on me. I had to turn the car off and restart it. On the way back home it wanted to die on me again but I pressed the gas to keep it on before the RPMs could reach 0. SES light came on with some codes in the middle of the test drive. Plugged up my scanner and got these codes. I should also mention I changed S1B1 o2 sensor around 100 miles ago and all spark plug and ignition coils around 2000 miles ago.
What should I do to try and resolve this issue? Any help appreciated.P1283 air fuel ratio sensor 1 bank 2
