my coolant temperature is varying between 90-108, and the engine light is on. I let it cool for a few hours, went back to check, the temperature was at 65 but the engine light is still on. What could be causing this? it just started this today. Thanks!

If your gauge is correct that is too cold for the engine to run properly, it could have set an ECT code and that light will stay on until you get the problem repaired and the computer reset.

Are those temperature readings in F or C? - Jim

Sounds like you have a faulty thermostat or are low on coolan. The coolant temp sensor may be failing and triggering the check engine light. 91°C is normal operating temperature for your Pontiac. HTH. -Jim

If those readings are C then it it too hot as Js mentioned above, but the light still could be the ECT sensor, a code check is still required.
