Answer to "Runs rough when temp sesor is plugged in"Pretty sure you have TBI. Before you put plug, wires, etc... try the fuel pressure regulator rebuild kit. It's about 40 bucks and takes about an hour to an hour and a half to do. The diaphragm gets dried out and rusted (it's part metal) and can make it idle rough enough to die. There are a few videos on you tube for guidance. Common problem with TBI.
