Check you plugs and do a compression test just for piece of mind.

Check the spark plugs for sure. On datalog what does it show your timing to be at when it sputters? Do you have a wideband, what does that show when it sputters? Check cap/rotor/ignitor/dist.

yea it has brand new plugs and wires and i checked the distributor it looks perfect and it ran real lean when it sputters but at idle its perfect air fuel ratio and it still misfires every few seconds

what kind of fuel setup are you running? do the spark plugs show your running lean or rich? make sure the injector plugs and wiring are good, this happened to my friend, thought he blew the motor only to find out it was a loose connection at the injectors.
