DI misfires...my saga of frustration
#41
BigDHenderson's 8/19 post reports car running o.k. after fully charging battery overnight. Seems to me this is a clue as to the origin of his problem - electrical voltage. Jaguars electrical circuits are extremely sensitive to battery voltage. Batteries frequently last for many years - "lasting" meaning there is enough power to start the car. But, they do degrade with time; and sometimes do not provide enough power to run some circuits fully/adequately.

Hate to rehash an old thread, BUT you sir are the winner! seen this 2x times now chasing a single (moving to other cyl misfires).
Summary,
IF YOU HAVE A RANDOM MISFIRE AND YOU HAVE DONE THE OBVIOUS STUFF, ODDS ARE ITS A MOTOR MOUNT.
