_________________________ UPDATE: __________________________
Meanwhile, back at the van. I replaced the idle switch, set
up as per book. no change, rechecked wiring, swapped ECU's
again. rechecked all grounds. checked with ox disconnected,
no difference. Still have heavy surge just off idle. The
only change comes with disconnecting the coolant temp
sensor. we specialize in only working on VW's and have been
doing this for over 20 years and we are getting ready to
call it quits on this van. I know someone out there has had
to run into this one before. Please, any help will be stop
someone from having a stroke here. It's not even a full
moon yet. It's too simple of a system but we just can't
find this problem. HELP

Hello Gentlemen, I have a 85 Vanagon that came in for a
severe surging just off idle, it's fine at half throttle.
We did a full tune-up, checked for vacumn leaks, replaced
all engine ground wires, checked fuel pressure. The only
thing we can do to make it better is to disconnect the
coolant temp. switch. We changed the switch with no
success. We swapped air flow box, ECU, checked idle
switches, and did a pin out test at the computer. If anyone
has any more suggestions they would be greatly appreciated.
Thanks guys, Bob.
