Sounds like you've tried everything - but change the temperature sensor.
I'd do that next!

Have you done the block test to test for exhaust gases in the coolant?
Do this. Methinks you have a case of headgasket-itisHave you done the block test to test for exhaust gases in the coolant?
Luckily our resident Mr. FixIt Jake can either sell you the parts to do this repair yourself or you can take it to him for a very reasonable price.Good luck.
