Ok so I replaced the EGR solenoid and EGR is functioning now. Fixed the EVAP leak and passed the EVAP test. But I failed the smog. The only driveability issue I'm having is hesitation when I first hit the gas from a stop. I came home and checked the flash codes and I've got 34 and 52. I already put a new VSS in. I'm going to take a look at the VSS circuit and see what I can see. But I have no idea what the Internal Control Failure is.

I've got high HC and CO Nox is good.


Lambda calc say's it's at .729
