Also could be a failed power valve if equipped but I`m sure the Holley tech went over that with you. Hard to say VIA internet.. Rich or lean? Do the idle adjustment screws make any difference? Are the plugs black? Notice any black smoke from tail pipe? Get back to us on partially choking engine and noting RPM change.. Good sign it is lean. Black plugs indicate rich.
