I would look into the misfire that came back in the code! more then likely the computer dropped your rpms the prevent any engine damage due to the misfire.

wel i guess ill try to bump this up. i want to check the plugs and wires for fire again but they are the back ones that are hard to get to. any tricks on how to get to the back 3 plugs and wires. i tried to get my hand down there and man thats a small space to deal with. thanks for the help by the way
