PONTIAC SUNFIRE ENGINE PROBLEM

1998 Pontiac Sunfire • 226,321 miles

Temp gauge started going up and down so replaced the temp sensor worked fine for a couple of days now my engine light comes on & gauge is below cold mark? Had diagnostic done it says its my temp sensor they cleared it & ran fine for a little while now engine light is back on & gauge not working again

Clearing codes does nothing. The issue is always there.

Thermostat may be a good start. Low coolant level could be the issue.

The last is a blown head gasket from overheating

Replaced thermostat, no white smoke coming from exhaust, or leaking in plugs, now when I started it today it didn't want to start & engine light still on could it be a bad thermostat? Please help!
