Mass Air code: 2324
Idle air control: 2231
idle air control valve: 4431

if it's the problem, you will get one of those codes, or all of them, who knows...?!?!
you still got the mass air flow and isv???? I also need a tps if you got it. if you can find those for a OBD I jetta 2.0 1993-1995 year range i will buy those from you now.
