The P1103 is showing as the wastegate solenoid and the P1105 is coming up as the fuel pressure sensor. I was curious if the wastegate solenoid not working properly would cause fuel cut and cause the fuel sensor to trip? Also, some sites list the wastegate problem as being a sticky actuator. Is this something I can possibly fix? Or is there an easy way to check it before tearing it apart? It's not a very old unit, less than 4 years old and maybe 5k miles. Not abused either, set at 16psi and capable of 45psi. The wideband shows the car surging every couple of minutes too, both lean and rich by a full 3 points in both directions. However when the car is moving, there's nothing happening unless I take my foot off the gas & let it coast, it'll surge several times and very quickly, then run lean and nearly die. Fuel filter has the same 5k miles. I read an older post on here suggesting a bypass of the fuel pressure solenoid vacuum line directly from the intake to the fuel pressure regulator. Any ideas? Suggestions? Everything is appreciated!
