[Shotimes] Help with diagnosis

[Kevin & Cheryl Airth]

Al:
 No stored codes from the misfires? Should throw a O2 code if much misfiring
occurs? This would help narrow down which cylinder or cylinders are missing.
Maybe not if it does it under WOT as then the O2 are not looked at by the
PCM?
Let us know how the condition of plugs/wires and plug wells?
