p0455 evap emissions system leak detected. Gross leak/no flow

p1136 long term fuel trim add. fuel bank 1 system too lean

p0301 cylender 1 misfire

p1250 fuel level too low

p0130 O/2 sensor bank 1 sensor 1

i shut off the light and it stayed off but the car is not registered yet and have not drivin it with the light off. where should i start?

 

Year? Engine?

 

Fill the gas tank. replace front o2 sensor if you have the 1.8 front left if it's the 2.8. then swap #1 (closest to the timing belt) and #4 coilpacks and see if the misfire follows. if it does, buy new coilpacks. rescan and see whats still coming up. i've never had an evap problem so not sure there, somebody will chime in.

just clear the codes and see which ones come back first of all. there may have been old codes stored.

 

Yep and even letting the clutch out too much (allowing the revs to go too low) can cause the misfire code. It's a 1.8T so in this case it's a nonfactor but on a 2.8 a bank 1 sensor is passenger side primary, not driver side.
