Quote: Kinda sounds like a vacuum leak or maybe a carb issue (internal blockage).
If you can't find an obvious leak, I had a problem with a factory street Hemi intake that had a pinhole in the floor under the rear carb going into the exhaust crossover. Took forever to find that. Had it welded up and it idled fine after that.
man, that one must have been a head scratcher! i have never heard of that, and probably would have never even thought to have checked that.
