It'll also give you a false code if you move the throttle, like revving it up... That's likely where your code 51 is from.

Also, when checking codes you do not start the engine. If it is blinking constantly with 1/4 second intervals, then there are no codes present.

Travis89Turbo, how did you gather the OP has a problem with the knock sensor/wiring when there is no knock sensor code present (code 52)?

OP, how much boost are you running? Are you referencing the stock boost gauge or an aftermarket gauge? I have not experienced it, but I agree with Travis89Turbo's first post, sounds like fuel cut
