hello im nathan and have a problem with my 91 mits gsx . when i start my car in the morning when it cold out side and the engine cold . it has a miss fire and runs ruff
and the mpi control relay clicks with the miss fire . i checked the relay and is good and
strong and clean . i tride to hold it closed to see if it would stop and it didnt .
i had the ecm replace and iac for other problems . and it is sill there .
i checked it this mornig and pulled of the connector for the power transistor and the car
stalled .like it will stay runing . so put it back on , not all the way on and the car runs
but when i wiggle it sounds the same as it plugged in . i did the same for the coil and
same thing . i dont know witch to replace or if it has anything to do with it at all
so if any thing you can do will be graet. i will be here if you need more info
