I just had my plugs wires and coil pack changed. O'Reilly’s checked the alternator is good. But it still jumps when I am going down the road.

Hi and thanks for using 2CarPros.

Is the check engine light staying on when the engine is running? If so, have the computer scanned to determine diagnostic trouble codes. Here is a quick video that shows how it is done. Also, if you cannot do it yourself, most parts stores will do it for free.

Let me know if this has been done and if it has, what codes were found.
