Anyone here with a 94' or 95' grand am with the 3100? I need to know what temp your car runs at. Mine runs at a constant 220/230 even on the highway. My beretta with the 3.1 never runs that hot and either does my Lt1 powered Z28. What gives?

Faulty thermostat would be the most likely guess. GM aims for a steady 200-ish degree's cruising with every one of their v6's I've experienced, including yours. Replace that thermostat, and I bet she runs normal again.
