Ignition coils can also malfunction, causing misfires in the ignition system. These will likely trigger a Check Engine Light (CEL) on your dashboard. A code reader can be used to check the trouble codes (P0300, P0301, etc.) that are generated by the misfiring problem.

At this point in time no engine light was present nor rough/shacking vibrations.
