2003 Jetta 1.8t Mass Air Flow

Asked by Oct 28, 2016 at 10:02 AM about the 2003 Volkswagen Jetta GL 1.8T

Question type: Maintenance & Repair

I was having problems with car turning off while
coming to stop or slowing down. Check engine
code indicated mass or flow sensor. Replaced air
filter and then sensor. Problem with car turning off
went away but now I have a ruff idle. RPM'S will
drop off as if car is trying to cut off then rev back
up while sitting at red lights. Check engine light
came back on amd threw codes p0171 and p0102.  
Rough idle seems to go away when maf sensor is
disconnected. Where should I go from here?
