My brake light and battery light comes on whenever the car is cranked, but when I start driving it goes off. I noticed lately in idle it has been running a little rough. But when I drive its good. Also, I noticed when the lights are on my car temp raises sometimes but goes down when I start driving again. Last night it did not want to crank (however it did try to turn over). It finally cranked but it was jerking and seem like it was going to stall. I pressed the gas and it started to run. I am lost on this one. I have replaced the thermostat already. What could be the problem?

Check the alternator charging. Clean all battery terminal connections and ground circuits and retest.
