when i baught the car it had 4 plugs that were the +2, and the other two were platinum 2.

it has misfiring and backfiring, i cant figure out what it is, 2 months later while it is misfiring i get a CEL, saying cylinder 2 misfire

i pull the plug on cyl. 2, put a new one in... no change, i reset the ecu

i then switched the cyl. 2 coil with cyl.1 coil, hardley any change, yet NO CEL

i put all new bosch +2 in, runs even worse

i took out the new +2 plug from cyl.1 (cyl. with the supected bad coil), and changed it with a old platinum 2, not the +2

now it runs like before i changed all the plugs

the engine died on me while i was driving, oil lights flashed, dont know if these problems are related...

i can definatly tell when its running on all 6 cyl. and only 5, when it doesnt misfire it will instantly get up and go, it will shift at 6500 rpm, but if it feels like its sluggish it will only shift at 4500 rpm at WOT and have the power of a NA legacy.....

i hope i have give some better details....
