Hi all,
        Last week I had a sudden stumbling backfiring '91 carat on my hands.
Looked like a possible green coax O2 cable failure as described by a
helpful listmember. I had tested several other fuel injection
components before the cable which were fine. I tested the cable for
shorting between the shielding and the core wire and it was ok.  Just
for  future reference if you experience these annoyingly similar
symptons, it turned out to be my coil that had gone bad. And not an
old coil either, it was bosch brazilian red in color, 3 years old,
don't bother with them. I also had a new silver bosch coil go bad
just last year (on one of my other vanagons) this coil was just over
a year old, I may have to try the low dollar mexican variety next
since the high dollar ones crapped out so fast. Anyone had similar
coil failures recently? How are the mexican bosch coils doing?
