    Dear Ferraristi,

    I just change and flushed my coolant and now have the exact symtoms as Andy. I mean exact ! It can't be random. Is there something I jiggled? The shunt in the transmission at the lower rpm is really wierd.

    Any Suggestions ?

    " Quote From Andy in 512 model specific forum "

    My '91 21k mile Testarossa runs roughly on a light throttle opening up to 2,500 rpm. It seems 'snatchy' and there is a lot of shunt in the transmission. It runs ok when the throttle is opened wide, and at higher revs. I thought this may be a manifold airleak perhaps, but has anyone else experienced it and what are the other possibilities?

    TIA

    Andy
