hello all, i ran into this problem about 2 months ago...and did a quick fix. basically, my intake mani was leaking. it was leaking at the fitting that takes vacum to the brake booster. went to advanced auto parts, got afittign, and stripped it..wrong size. it has worked until now...do any of you guys know what kind of fittign (thread, pitch) i need to get? any help would be awsome....cuz shes idling at 500 now instead of 800 like usual. and it is 93 cx with a 96 ls swap.

thanks,
arthur
