   can some please help me find out why my car is idling at 1500rpm, ive worked on all the sensors and i want to rule out a vac leak.
   
   The hoses i know of are:
   
   Under throttlebody to brake servo
   Front of throttlebody to inlet cam casing (small 8cm hose)
   
   Someone mentioned there is one to the underside of the inlet, can anyone help me locate all my vac hoses so i can check theyre not leaking please?
   
   Thanks in advance for any replies.
   Paul.

   I think you can use easy start or carb cleaner to find vacuum leaks, just spray some where you think a vac leak is with the engine running, and the engine should rev up slightly/run differently.

   same here, its what i'd use to find air leaks into the inlet
