Hey, I finally got my problem sorted out by changing the ht leads(spark plug leads) and coils packs.got them of a evo 9 engine because they are all the same.if you arnt sure change your spark plugs or clean them.go for a drive when its bucking ,take out your spark plugs and they should be all the same.If one is kinda white it means the fuel hasnt properly burned without a proper spark in that cylinder or at least that is the theory.
