Sounds like what's called a "dead Cylinder". Have it tested for the codes and the one number on the end of the code will tell you which cylinder is misfiring. A code like P0303 means it's #3 cylinder. It could only be a faulty fuel injector, but be ready for something worse. Once you know which one, do an ohm-meter test on each injector unplugged. If it shows a much lower reading on #3, just change the injector. If no difference in readings, do a compression test on all cylinders with all plugs out. This could show you've a faulty valve on a cylinder with very low compression compared to the others.

Yup, that's best. Lot's of luck Brother Mark.
