at idle my 1987 944 n/a hesitates slightly every couple seconds. im guessing that i could have vaccum leaks which are causing this, well the engine rubber is 20 years old after all. are there common areas where these leaks occur and how exactly should i go about detecting them? should i also have a look at my "idle stabalizer unit"? I dont believe that the motor mounts or balance shafts are to blame...which company has the most affordable rubber engine components like as the intake boot and such?
