map sensor will make you run rich as hell. some map sensors are mounted to the trottle body, very very common. others are mounted on the fire wall, in my case the old engine had one on the trottle body while my new engine needed one that mounted to the firewall. it may sound like you either need a new throttle body or to find a new map, but you can reuse your old one it may be made to mount on the TB but a hose will slip riight on the end, then you just have to get the vaccum hoses right.that may have been useless to you but it fixed my civic that was getting like 7mpg. a oil change will be verrrrrrry nessisary, alot of fuel will get into your oil running that rich. good luck
