K well I just pulled the three across the front. (Ill be purchasing the iridium plugs very soon) And Im back to full power! sweet! I noticed that the white coating around the electrode on all three was worn/Burned off. I suppose the plug was arcing out against the block? Any way, would that be due to them being platinum and not iridium? just wondering how to avoid this in the future. and thanks for the replies guys.
