hi, how can there be no power to the coil if its running and drivable, if i take the revs over 2k the car performs how it should and runs on all 4 cylinders, its only when it tries to idle it switches back to running on cylinders 2 and 3 , ive read about wiring being damaged back from the coil plug but ive checked back as far as i can and cannot see no signs of damage, im thinking would the maf sensor need replacing as when i sprayed the carb cleaner in the intake next to it it ran perfect even at idle.
