A question for you CIS(or and FI) gurus out there. Replaced the injector and it did not help

[mabatzis at gmail.com (Michael Abatzis)]

john, when does it stumble? only at WOT, or any acceleration? does it
matter if it's hot or cold? is it always at the same rpm? if you have
an ignition problem, it's likely intermittent, which is of course
harder to find.  check/wiggle your plug wires while revving engine,
and do the same with the hall sensor connector on the distro.  at
higher rpms a bad plug/connection is more likely to fail.
