Hi guys

My 996 3.4 is showing the fault code "Cylinder 3 misfire".

Should I start by changing the plugs, or the coilpack?

Thanks in advance!

It is usually wise to switch the coil pack to another cylinder - then clear the codes and start the car. If the new fault follows the coil pack - then replace the coil pack - if the fault stays on the same cylinder then replace that spark plug.

Also, first check that cylinder for a loose electrical connection or loose spark plug - it can happen.

I had the same code. Turned out being a failed intake lifter. Replaced them all to be safe.
