Changed coil, still running rough

[dk2]

I have searched the threads and still dont have an answer that helps. I changed out a coil a few months ago after the light came on and it started running rough. That fixed the #2 misfire. Well, a month ago the light came on and it was running bad again. Checked it and the #6 was misfiring. Next day, light went off and it was running fine. Today it started back feeling like it was misfiring, but no light came on. I went ahead and changed #6 coil (which by the way, the rear bottom bolt of cover was a b*tch) After changing the coil it still runs the same. I guess it wasnt the coil. Any advice would be helpful. Thanks

All your coils are in process of going bad. Change all of them.

Check the electrical connection to the injectors and ignition coils. It wouldn’t hurt to put a little dielectric grease on the connections.

Are you changing the plug on that cylinder when you change the coil? They can get fouled when the coil misfires.

I changed the plug out with the coil and it still is rough, only at full acceleration now. Up to mid throttle it runs good. I can hear it bog down at WOT.

Try replacing your fuel filter.

Thanks, Joe. Maybe I need to yell?
