put a d15b in my del sol and the harness didnt have a map sensor plug on it so i had to manually wire it in to the ecu harness but everytime i wire it in the car idles low but the check engine light goes off then the car will shut off but when the map isnt wired up the car runs fine just throws a map code? i wired it into slot d17 need help to make sure i did it right?
