My car just started running very rough last night. I checked the trouble code and I it is showing a cylinder 4 misfire (P0304 I believe). I tried swapping the plug and coil pack with cylinder 1 and I have also checked the Ignition Control Module out, no change. Should my next step be checking/changing the fuel injector? If so, are there any good how to guides you all know about for replacing those? Any help is greatly appreciated.

Thanks

Well I found this great link for changing the fuel injectors

http://www.a4mods.com/index.php?page=webcontent/pages/injectors.html

so I swapped 4s with 1 but still have the misfire on 4. Where do I go from here? Wiring harness to CPs or fuel injectors? Any way to check these out without taking it in to get it done?

Thanks
