Installed my F&B 70mm throttle body Saturday; replaced my plugs while I was at it (autolite 5224's). Got the standard high idle hovering around 1250 then slowly dropping to normal idle speeds. Been driving it for two days now and the butt dyno says everything is GOOD, pulling real nice, more torque; lights up the tires at will etc; all around running really nice. By today (Monday) the idle has settled in to normal and life is good. Anyway about 10pm I run out for a pack of smokes taking it easy (saving gas, you know how it is) when all of a sudden engine losses power and dies; check engine light comes on and won't start back up. After about 5 minutes it decides to start and I get it home before it dies again. Put the SuperChips on it and it pulls a P0068 code; display reads (Correlation MAP sensor signal does not correlate to throttle position sensor signal. Possible vacuum leak.). A vaccum leak though possable isn't likely; anybody have any ideas / experience with this?
