Fellow listers,
Any suggestions welcome!
Have been having a bit of a time trying to find the cause of a miss (or
pulsing) experienced when backing off the throttle, or holding a steady
speed. There is also a slight popping from the exhaust as the throttle
is let off during shifting.
Accelerating has no miss and higher speed cruise has a less noticable
miss or pulse.
