If the Check Engine Light comes on, and diagnosis finds a trouble code, or codes, for misfires, it might be caused by insufficient valve clearance for the affected cylinder. The valve clearances should be inspected and adjusted where needed.

A loose or corroded ground terminal on the driver's side of the cylinder head can cause a rough idle, misfires, and there may be trouble codes. Restore the ground to the cylinder head.
An electrically shorted air flow sensor can cause a crank-no start condition. Diagnosis may show that ignition spark is normal, and there are no trouble codes stored.
A wire inside the head light switch can fatigue and break over time causing the head lights to be inoperative. There is an updated head light switch to fix the problem.
