And speaking of that small type of vacuum hose, on the 2.1 one of
these hoses runs to the rubber boot at the idle stabilization valve. A
crack at the small nipple where it meets the boot body could open up
at times, or not, depending on hose position? Regardless, it's a
potential source of a vacuum leak.

Repaired that part on my 2.1 just recently. Not sure how long repair
will last but I sleeved the small nipple with (fuel?) hose and covered
all with "Industrial" Gloop which is probably a knock off of "Goop"
but not "Gorp"   ;)

Of note, was intrigued to find a restrictor in that small nipple. Same
purpose as restrictor used on the 1.9 for the EVAP system?
