I have a 83', 1.9L fuel injected =
Vanagon. I
have replaced all engine gaskets, (including heads) water pump, =
thermostat, fan
switch, fuel filter, O2 sensor, piston rings, complete tune-up and =
probably a
half dozen other things I can't recall right now. I have also =
checked out
most off the sensors (coolant sensor #2, injectors, and etc) and =
any others
my equipment could do all checked out within specs. I used a =
vacuum gauge to check for exhaust back pressure (cat converter) =
looked
good as well. The problem I am having is that the bus idles badly, =
shaky
like. When I take it for a road test it's breaking up at low RPMs =
and when
I rev it real high it also breaks up. It kind of sound like it is =
running
on 3 cylinders. Another item worth mentioning is that if I let off =
the
throttle just right it kicks in and sounds and runs like it should (much =
quitter
and a lot smoother). I had an exhaust gas analyzer hooked up to it =
and the
mechanic adjusted the CO supposedly within specs. He also checked =
the fuel
pump pressure and found it to be OK. Any logical comments are
appreciated. Also the recommendation of a excellent VW mechanic in =
NJ
would be helpful!
Thanks,
Otto
