Re: P0300 Random Misfire 2.4L Quad 4 SOLVED!

Have you narrowed it down to which cylinder is misfiring?

Pull vac line to f/p regulator and check for fuel......

I know this is a year late but was wondering if you had solved your issue with the miss fire? I have a very similar situation which I have been trying to resolve for a month.
