Hot idle issue ?
Having a hot idle issue, cold start, cruise and boost AFR's are all ok, but coming to a stop when the engine is hot the AFR goes to 16 or more and the idle starts hunting. Tried isolating the ISV and hot idle seemed to improve but AFR everywhere else was rich. Planning to pull the inlet manifold to check hoses and ISV unless anyone has any other ideas ?

Check the top or Throttle body the Idle Screw, maybe the rubber O ring is perished...Other than that.. Get about 15 feet of bulk silicone hose and look at LR website Good Vacuum Diagram.. 30 year old rubber.. Toss it.
