A6 misfire
I have a misfire on my Audi A6 2.7t Quattro. It started on Cyl #3 and
4. I put in some fuel injector cleaner and replaced the plugs and Cyl
#3 misfire went away. I replaced the coils on Cyl #3 and #4 but it
still misfires. This is a very strange misfire. It misfires at idle,
off idle and under load but seems to go away at 2000 rpm with no load
and 2800 with load. This all started on the same day. Could it be fuel
injectors?

Is the compression OK? There's a scary chance that the head gasket blew
out between the two cylinders.

ok, I'l confess to not knowing this for certain, but given the 2.7t is a V6,
does Audi number the banks 1-3 and 4-6, or do they stagger (odds on one side,
evens on the other)?
