No codes, but during my OBDII scans I am showing these failed tests: $21 EVAPI (Evaporative Fuel Tank Pressure Initial Low-High...) $25 EVAPRISEL4 And yes the car runs poorly. Feels like it has a misfire, but I'm sure it's not an electrical (plugs) misfire. Poor power, the fuel press gauge fluctuates almost in tune with what appears to be the misfire (again, it's not). I assume I need to test the evap system. Any way to do that short of a shop doing it?
