Help! Can't start it up...(2)

     Hi Q-listers,
     
     Many thanks to Dan Simoes, Mike Watz, Barry J. VOX McCabe for sending 
     me the advices/suggestions.  I really appreciated your help, guys.  
     Anyway, after carefully checked all areas you'd suggested, I found 
     nothing wrong at all.
     
     To make a long story short, the problem on my 90 is: the vacuum hose 
     adapter (w/ + shape connected to the ISV) lost the bolt which plugged 
     into one of its extra leg.  (Humm...this bolt was put in by a $89.95/hr 
     stupid/moron mechanic @ Zumbach--when I had 60K services back in June.) 
     Since there is no plug into the extra leg, the vacuum pressure to the 
     ISV line is dropped to zero.  That's why my 90 was started and fought 
     to the idle speed--but it couldn't hold the idle.
     
     After I plugged the extra leg of the hose adapter w/ a piece of a 
     rubber cover, the engine cranked up w/ no significant problem (w/ the 
     idle 750 rpm).  :)
     
     Thanks again guys,
     Nat
