Misfire engine code what to do?

[Ben Schepper]

My check engine light came on this weekend and told me that p306 engine misfire in cylinder six. I was wondering if any one else had gotten this code before and what they did to fix it. I already cleaned my injectors with some fuel cleaner.



My guess was its either plugs or wires. Both of which i was going to change tomorrow.

You guessed correctly. Plugs and wires would be the proper fix. A misfire is usually caused by worn out plugs and/or wires.



If your injectors are clogged, you would get a lean condition or an injector error.

Cool hopefully i can pick up a little power. Im planning on getting some wires from the new site sponsor.

Please do not use anything but Motorcraft Spark Plugs. No Bosch, No NGK, no Split Fire.

You can have 1 bad or weak injector on just that cylinder......

Plugs, wires, and filters first before any thing else..
