Question

I got the P0304 code car misfire (small) but most of the time the engine runs smoothly. How can I fix it on my 2002 Lincoln Town Car 4.6L?

Answer 1

Hi there,

This is usually a faulty ignition coil that will cause this. Sometimes it takes just the right conditions for the coil to fail then it will cause a misfire. I would usually start by replacing the ignition coil or swapping it with the one next to it, then see if the misfire code moves with it as well.
