brandon bowles · 08-29-2010, 04:01 AM

ok i have fix the problem change the MAF back to the stock one and now the car runs great till i hit fuel cut. so now i have to get a regulator to build up the fuel to bout 58psi right? cause it still has the stock regulator which produces 38-40psi. once i hit fuel cut i have give it a min to build the fuel pressure back and then go again.

Jebus.... I'm gonna smack someone...

OP's describing limp mode.... there's a critical fault in the system.

Code 51 is NOT related to ANYTHING to do with knock.

Code 52 DOES store in the ECU; Code 51 does not... it's one of the few real-time codes.

We done now?

OP, how much boost are you trying to run?

ok now i have code 14 an 34. 34 would that have anything to do with wiring from the boost gauge being cut? 14 not for sure. now when i start the car and go down the street when the car trys to boost it acts like fuel cut in 1-4 gears and in 5th but after hitting it like 3-4 times it will boost all the way up to 9lbs and act fine as long as i dont hit fuel cut. I HATE FIXING OTHER PEOPLES FUCK UPS!!!!!!
