[alfa] Re: no more than 5000 rpm????

[Joe Elliott <jee@xxxxxxxxxxxxxx>]

My GTV-6 has had this problem twice, both times electrical.  The 
first time it was the main terminal block on the left front inner 
fender that joins the fusebox, alternator, and battery (dirty 
connection).  The second time it was a failing ignition switch.  I'm 
not sure if these issues affected injector driving or (more likely) 
ignition, but in both cases there just wasn't enough juice to do it 
as often as is needed above ~4500RPM.
