Greetings!
I have been off the list for a 18 months or so, but still working away
on my 87 Wolfsburg.  My son and I exchanged the engine ( Fast German
Auto longblock) last week, and I replaced the air flow meter with a new
one from Bus Depot.  When the engine warms up, I have a pulsation in the
idle of 100-200 RPM.  The idle switch is engaging, TII sensor is only a
year or so old.  When I disconnect the idle stab. valve, the pulsating
stops.  Any clues?
Thanks in advance,
Chris

Vanagon only dreams of)
72 Karmann Ghia ( air cooled rules!)
