Misfire code #2cylinder reared its ugly head.
Changed all plugs
Changed #6 ignition coil (thought it was # 2 coil)
after 3 months of same misfire and sluggishness changed #2 coil
Still same problem. Could the long time with new plug BUT SAME OLD BAD COIL have ruined the new plug that was installed?
