Can anyone tell me what the fuel pressure should be for a 2007 Chevy Classic with 5.3 vin Z? I am trying to fix codes p0172 and p0175. My pressure is 54 psi with engine off and 60 psi with engine running. Running it is bouncing fast. Long term fuel trim is -19.5 both banks. New MAF and air filter. Thanks.
