did you get it running with the ether before or after you tested your plugs? and if your fuel filter is horrible enough it definitly could cause the car to run like shit, hell, having rust in my last 2g fucked my fuel filter so bad it'd run good but the randomly the car would start jumping and just die..
and i've also heard the 3k's are horrible with coilpacks aswell...never had one so i can't comfirm it but if it helps you man, when both my ecu's went out, both times my car would turn, but have no spark...
