I NEED HELP....So my car over heated and I replaced the thermostat. It was over heating on the freeway only. Now my 07 hybrid won't start unless I try a couple of times or several times but when it starts it won't accelerate and rpm doesn't go up. Oil looks good no signs of water mixed. If I turn car off then start it again it takes a few times to start it doesn't even turn over until it actually starts. Then it will drive but will not go very fast and the rpm does not really go up to high.if I shut it off it starts from the top of this message all over again. Engine light and a little wrench symbol stays on I even disconnected battery and both lights stayed on.
