You were commenting on loud injectors, and the only thing that listens to the motor is the knock sensor. That's why I went down that path.
yeah. I just know its something to do with the large injectors. Cuz I got this code about a year ago when I was stock and had just got my 1000cc injectors installed. All I had was walbro fuel pump , k pro , and after the injectors I got this code. My friend said he knew it wasnt misfiring cuz I would know, hear it / feel it etc etc. I disabled obd2 and never had a problem again. I ran an 11.81 after going turbo and with the obd2 still off. I think the obd2 sensors are to sensitive and want to sense everything as stock so when you are not it picks up wierd shit. idk just a hypothesis.
