Engine Mechanical problem
2004 GMC C2500 V8 Two Wheel Drive Automatic 135000 miles

last night when engine started it ran very rough, missing badly. Turned it off and restarted after a minute, it stopped missing and ran pretty smoothly, when started this morning it was missing badly again and has a rather loud knock/ clacking sound from what appears to be the drivers side in the lower part of the engine. I changed plugs and wires but there is still a miss and knock.

After it warms does it run smoothly? The knocking sound sounds like the flex plate is coming apart if you told me correctly " rather loud knock/ clacking sound"
