Ferrari Mailing List: Re: 328 fast idle question--hit a bump?-reply

[Robert Rehkopf (CaptRehkopf]

Doug.

1988.5 vin 77688, full service by Norwood about 1500 miles ago, about 10-15
mph. I thought my plenum was on the passenger side?

Thanks,

Robert Rehkopf.

Hey Robert - asking for professional advice from this group is akin to 
asking Ferrari Bubba to explain why he didn't become that piano player at 
the Mustang Ranch.  heh heh

Nevertheless - here goes: Need some more data - how old is the car?  Last 
service?  How fast did you hit the bump?

The CIS induction system is very very basic mechanical fuel injection.  It 
gets its enrichening signal from a balance beam teeter totter affair 
activated by the down draft volume of air requested on the air horn paddle. 
Too much unmetered air and it quits, too much fuel and it runs like a slug. 
So, that said - I would vote for too much air.  A vacuum line fell off. 
Perchance from the "body, air delivery" [I'd say air plenum chamber - guess 
it doesn't translate well] drivers side (if you are a LHD car).

Gimmie more info.
