ugh, i hate my cars sometimes.....
changed the spark plugs, they looked ok, i dropped one before i had a chance to look at it so i dont know if the gap was closed by the drop or by the engine, it was only half closed anyway...
took it for a drive, and floored it, saw some very minor kr, then it missed for a second and shot to 8* kr, let off immediately, then once i stopped i heard this GOD AWFUL rattling, revved the engine and it went away.
Cliffs: i think the supercharger coupler went or a bearing went in the blower. it does have 150k on it.....
