Hey all, I've just got a 2005 fiesta st and have been having problems with rev hang when she is cold that goes when warm, then I get a rough/lumpy idle when warm, I've had the throttle bodies cleaned and can't see any splits or holes in the vacuum pipes, no fault codes when plugged into diagnostics, anyone got any ideas?

There's a pipe under/in the inlet manifold which splits sometimes?
