Hey guys, been getting my check engine light showing. It only lights up when I'm giving it gas at idle or driving down the road. It goes away when I put it in neutral and the rpms go back down. Apparently it's high fuel temp warning. My question is... Is this likely a bad sensor or if it's true, what problems would I experience with hot fuel?
