I did the obd2 - obd1 ecu swap in my 98 dx 1.6l d16y7 so i could get rid of my 2nd o2 sensor. Everyone told that a p06 would work. But, it doesn't seem to be the right ecu. The engine light came right on after we plugged the ecu up. And, the throttle revs back and forth. The car has no pep at all.........it's super sluuuuuuuuuggggiiiissssshhhhh. I don't know what code it is throwing, because it only has the obd2 plug under the dash and the code reader couldn't detect anything. Thank You for your help. Would a p28,p30,p72 be a better ecu swap? Why wouldn't the p06 work?
