Well, still trying to figure out what is going on with this piece of junk. It is definitely not the fuel system I took the FMU out, put all the
VAC lines back to stock. Then I tested the pressure with a mechanical gauge and let the car idle for 30 minutes and the presseure held at 44psi.
Well, during that same evening the SES light came on. When I finally scanned the car this morning the fuel trims were real rich and when I checked the DTCs I trew P0420 CAT, P0440 EVAP, P0106 MAP. So I checked my gas cap to see if I tightened it up after messing with the fuel system and I didn't so that took care of the P0440 but would having the gas cap loose cause the MAP to throw a code?
