starting points for jetta problems aka I hate cars
AHHH HA! Found it! it connects to the (NTC) Temperature Control.(Bentley's
page 86 track 28) That's pretty scary when we cite Bentley's pages like
Bible verse. 8-)
Wonder how that would cause the rough idle? I could understand when it's
warm because it would read low and rich the mixture, but why when it's going
from cold start?
Oh well at least it's running. 8-)
