Was on my way to work and got a check engine light while driving then the fuel was cut off by the computer and it threw a p1264 code. Started the car up and my throttle felt off as if the car was lacking power. Another thing when i was going back home i was idling at a stop light and the car read a positive 35:1 stft on oft. The car had a slightly rough idle and was like burping or misfiring or something and it went away when i drove off. Been on a 93 plus tune for months and had it retuned but the problem is still there. I have no clue about this, can anyone help me figure this out.
