The actual codes will help the search for an answer. Many chain autoparts houses will do this for free. A code scanner will soon be the first tool in the old tool box so might be a good investment. http://www.eautoelectronics.com/

have not been able to get the exact codes but mechanic says that the codes point to the plug wires or plugs but something is messing up the plug wires each time they are changed.

after putting on new plug wires this weekend the service engine light was turned off and the truck ran great for a day and half then the service engine light came back on. Took it back to the shop and the machine said that the truck had a bad catalytic converter on bank one. Does this make sense? the truck ran good for a few miles then it starts missing and this is becasue of the catalytic converter? Could this cause the plug wires the have trouble on the three sets that i pt on it in the past few months? HELP PLEASE!!!!!!!!!

Don't know about causing the plug wires to fail but as backpressure builds performance deteriorates.
