My '94 844 developed a large amount of engine vibration after being worked on by an independent shop (who extracted a fractured spark plug that had fallen down inside the combustion chamber !! Talk about a pucker job....)....Anyway, I feel lots more vibration through the seat, doors, armrest, even the shift lever, particularly when stopped in gear (automatic). My instrument panel cluster has vibrated loose from inside the dash panel (the VERY poor design inside caused the little plastic extrusions, which the clamps tighten over to hold the cluster to the inside of the dash, to break at their base). That's how much vibration I've got.

Any ideas ? Engine mounts seem to be OK, but I've only had one opinion.......and it doesn't seem to me to be a misfiring cylinder.....
