Did you check the fuel filter?
or possably the catalitic converter is cloged, check the exhaust pressure.

Hey there boatright33,
A few things things immediately come to mind.
There may be a problem with the engine controller. You could check the
ODBII onboard diagnostics. Auto part stores will usually do this for
you at no cost.
When you pulled the ones that were/went bad, how did the filters look? Could there be particulate matter still in the tank causing them to fail.
I always put this one off until last. Check the injectors. Are they gummed up?
Let me know what you find out
Mike

Any suggestions?
Thanks

Check for a bad distributor cap and or rotor..........a bad cap and or rotor can caues firing (cross fire)across the terminals and introduce spark to the wrong cylinders at the wrong time.......
hope this helps.....good luck!
