CautionSafe to drive short distances. Avoid highway speeds.
Most likely cause
Ignition coil failing

The ignition coil creates the spark to fire each cylinder. When one fails, that cylinder misfires — causing rough running, especially on cold starts or under load.

Check this first
Swap coils between cylinders

If the misfire follows the coil to the new cylinder, you've confirmed the coil is bad.
