Re: Idle Stabilizer

[Jeremy R King <kingjer@eng.auburn.edu>]

BTDT!  A friend at Valdosta Foreign Parts pointed the problem out to me 
originally.  He made me a deal on a brand spankin' new one.  We put it on 
and the first thing it did was collapse.  The only thing we could come up 
with was to insert a spring (like in radiator hoses).  I haven't done 
that - mainly because I'm a firm believer in solving the problem, not 
curing the symptom.  I usually see 22 MPG around town and 25 MPG on trips 
(75 MPH).  This seems low - and I think my rubber duckie could be one of 
the reasons.  Also, (boy this is gonna sound "duh") lately I hear a 
mighty powerful sucking sound in my intake manifold, just after the 
throttle.  This is very normal, right?  Air moving through the thing and 
I just haven't noticed it before?  Or is this the $$$ sucking culprit 
Bruce was discussing?

Thanks.
