You are buying a USED mostly complete GM 454 TBI unit numbered 17094020, complete as pictured.  The throttle shafts are not loose and they are not frozen.  This was pulled from a 1994 Suburban with a L19 454 engine and a 4L80E automatic transmission.  It is missing the IAC motor but everything else is there.  Worked when removed but I would recommend tossing at least a gasket set at it because it’s been sitting for a while now.  Selling this as-is -> for parts only!  Shipping will be insured FedEx ground to anywhere in the lower 48.  Feel free to contact me if you’d like to see some more pictures or have any additional questions.
