If it's stock and you live in the US, then it's computer controlled.

The defining plug is on the driver's side front corner. That's the TPS for computer controlled q-jets. You have that plug, you have a CC q-jet. Don't have that plug, it's a non-CC q-jet.
Also look at the distributor - does it have a vacuum advance can on it? Yes, non-CC. No, CC.
