Hello, I have a 2000 GT with a Kenne Bell 2.1 and my fuel pressure get up around 60 psi once the car gets up to temp (open loop). When its in closed loop (before operating temp is reached) the fuel system works fine, goes up to 55-60 under full throttle like it should with the boast a pump. Once it reaches temp it idles at 50-60 and goes to 65-70 under full throttle. It finally threw a code P0172 bank 2 rich. Any ideas would be helpful.
