i got a 1990 integra da9 from some kid claiming that the car has never been ****ed with but two days after i buy it i just randomly shut off on me in the middle of traffic. after two minutes of the car being off it will turn back on (not by itself) then run fine for a bit then it happens again. i took it to the shop nothig wrong with it engine wise. but then i took out the ecu and found out it was an auto ecu . could this be the reason why my car shuts off on me randomly???
