I have an 86 vanagon with a 2.1L. I just fired it up after rebuilding the
engine, and it's not running very well at all. The idle is rough, and it
seems like it's missing. First thing I did was run a compression test, and
compression was ok (125 - 130) New spark plugs looked like maybe it was
running rich. Wasn't sure if I plugged the fuel injector wires in correctly.
I marked them when I pulled the engine 6 weeks ago, but my marks weren't
very distinct, so I kind of had to guess. It doesn't seem to make much
difference if I plug them in the other way though. I'm wondering what is the
next thing I should check. Maybe the O2 sensor? Or maybe the Idle Contol
Unit? But it's running bad all the time, not just at idle...I know I put the
distributor drive shaft in 180* out, but I turned the distributor around,
and the timing marks line up, so it seems like the timing is ok. Hopefully
someone can tell me what to check next. Thanks.
