Hi all,
I'm updating on Vinnie's (my 85 Vanagon) condition. The problem was-driving
around town ok, but 30 miles or so out on the highway the fuel would
gradually get richer and richer until finally the fuel injectors would
straight stream. (Test at mechanics determined this.)  Symptoms were like
drivers foot slipping off gas until it quit running during deceleration,
like on an exit ramp. Well, now the problem has evolved to the point that
it is happening 5 mins or so after start up. No longer just a highway
problem.
Recap of replaced parts include:
new cap/rotor/plugs
fuel pressure regulator
ignition module

Cory (my mechanic supreme) has performed extensive tests and we are at the
conclusion that the ECU is the most probable culprit. I'm just playing
detective to the extreme and well, here we are.
Unplugging O2 sensor (to get to defaut mode) results in no change at idle
or revs from idle
Have yet to drop cat converter as the bolts are extremely frozen

Any new insights?
Any one have the lowest priced source for an ECU with any warranty?

Thanks,
Dave-85 Vanagon "Vinnie"
