I have a 2005 Saturn ion with a 2.2 in it. When the car is cool it runs like a dream. But as soon as it hits the normal temperature it starts acting up like it's about to stall out or it's only getting 1 gram of power. Like it's starving for fuel. Yes I have replaced the altnator, plugs, coil, the whole thermostat. And flushed the radiator hoses. It's just like it's starting for fuel and I'm out of options. Could you Scotty or anyone else help me

often a bad temp sensor for the computer, i would start there. Pray it's not a blowing head gasket as this video can test https://www.youtube.com/watch?v=QA7KVQq9vKA
