yup thats what its doing, high idle / surging, havent got the coolant lines connected,
but it also sounds like there is a huge vacuum leak, only getting 10" on the guage,
i cant physically see any were on the inlet were it could be sucking air in,
* is there a position for the intake air temp sensor on a late model redtop inlet?
test drove it tonite, first time as turbo,
oooohhh baby, cant wait to sort a couple of niggly things and shes all on.
