Thanks for your help, listers.
The proper VCDS tool pointed at MAF - low signal after swapping in new
spark plugs and swapping ## 2 and 3 ign. coils. The old sparkies were
mostly black and unburned fuel comes out the exhaust. Soaking now the MAF
in alcohol in a faint hope attempt, but a new 1 will be on order soon. Any
MAF brands to avoid?
