i have a 92 integra da. has a gsr motor turbo'd, i swaped a built motor in the car, at the same time of the swap i put the turbo setup on it. ever since i put the gsr engine in it. the car started every time, i got the proper base map on the car. i parked the car for 2 days waiting the tune then i go to start it on day and nothing. it just cranks but no start. i unpluged the mad sensor and the car started but wouldnt idel, i had to keep my foot on the gas to keep it running, so it staled out onse i let the gas out. i tryed restarting it and it was back to just cranking but no start. i then plug the map sensor back in. and it fired right up but died right away. with the map sensor pluged in their was no throttle responce at all. so what it comes down to is i get one start with the MAP pluged in and one stat with it un pluged. unpluged i can keep it running with my foot on the gas but i get alot of white smoke, and its running very bad. this issue happened over night. any ideas where to start from? thank you for the help
