Ok folks - could use some help. The sedan (95.5) has
developed a stumble - at idle and through all range of
I'm pretty sure it's a coil. Here's why...
new plugs (1 week)
new plug boots (24hrs)
swapped new pos in both slots - no change...
so tonight I pulled the coil harness (all 5 coils and
the cover) out of the avant (also a 95.5) and stuck in
in the sedan - stumble is gone.
So got to be the coils right?
But when I unplug the injectors one by one - all seem
to degrade performance. So I suspect a coil is just
mostly dead - notcompletely. How do I figure out
which coil is dying???
For what it;s worth the sedan is running stock
software with a FMIC and stromung exhaust.
