First off kudos to all of you here who share tips and experience with others. I'm impressed!

Any thoughts on these codes, which I've accumulated in this order:

P0171 System Too Lean
P0440 EVAP Emission Control System Malfunction

I have had a solid CEL for over a month, just reset it after reading these codes and it came back on after about 10 miles of city driving.

The first sounds like a bad MAF based on reading threads here, but given the second I wonder what else it can tell us, not being an automotive expert myself. Also, is replacing the MAF oneself a gargantuan task?

Oh yeah, 1997 Jetta GL, no mods (that I know of).

Thanks, ray
