I've had my hot rod cams installed for about a year and a half now, and have consistently had the same problem of hanging rpms. It has come to my attention recently that it could be a vacuum line problem, i.e. there could be a knicked line in there somewhere that's causing the engine to breathe improperly hang the rpms when the engine slows from a higher rpm to a lower one.
Can anyone help me identify how many lines there are or which it may be that's causing the problem or even how to identify a line failure so I can do the work myself?
Any help would be much appreciated
