Answer 1

you may have 1 or more bad ignition coils. You can check each one by pulling out each coil at a time when the car is off, put a spark plug in the ignition coil point it directly at the intake manifold (dont hold it or touch it, it can shock you) and you can start the car and see if there is a spark. Do this with each coil and see if there is one or more that is not firing.

- Faulty power transistor unit built into ignition coil
- Ignition primary circuit is open or shorted (circuit to ignition coils)
- Ignition primary circuit poor electrical connection (circuit to ignition coils)
- Faulty ignition system condenser
- Crankshaft position sensor circuit
