Hi,

Did you check for diagnostic trouble codes? I would start by determining which cylinder or cylinders are causing the misfire and then start with those cylinders by checking plugs, wires, and so on.

Here is a quick video showing how it's done:

I realize most people don't have a scan tool, but oftentimes a parts store will scan it for you at no charge.

Do this and let me know what codes are retrieved. Also, let me know if you have other questions.

Take care,
Joe
