have you replaced or rebuilt any of your coilpacks yet? so this has to be either coil, ecu, or electrical wiring. did you clean the connectors that connect to the coils using electronics cleaner, those get hella dirty from everyday driving. make sure the connector clicks onto the coil as well, make sure the coil is bolted down. look at the pins, make sure there isnt one bent or pushed into the connector. if you shake the coil and hear metal stuff inside moving, you need to rebuild the coilpack. you can also bring them to like autozone or something, and have them tested for spark. if your battery terminals are really loose, or the ground has lost connection, then you should start worrying about the ecu. if you lose battery ground when the motor is running, it will ground thru the coils back to the ecu, frying the ecu, hope this didnt happen to you.
