could my old spider assembly have done this or is there something else i am over looking

 

Spray some carb cleaner down at the bottom of the trottle body and see if you have vacume leak.The shaft that has the platews on the bottom has seals that go bad.My truck a 94 had a similair issue.I traced to to the vacume leak on the bottom of the throttle body.

 

*** uming your vehicle is the same year as your SN you have 4 02 sensors in your exaust system I would check those also.
