What brand of plugs and cops did you use?

 

motorcraft plugs and the cops i have no idea

 

Could this be the transmission? I read about the Torque Converter going bad or the tranny getting flushed and fixing it. Hope its the cheaper of the two!

 

No. The problem you're describing sounds like a misfire. Since replacing the plugs (which I assumed you gapped correctly), have you had the computer scanned? Codes would be helpful.

 

Where did you buy the cops?

 

I havn't scanned because I never got a CEL again. Makes since it could be a low level misfire and the light isn't comming on. I made sure all the plugs where gapped correctly but the CoPs on the other hand where relativly cheap. Maybe 100$ for all 8. That could be where my problem is comming from, cheap cops.

 

The cheap Ebay cops are generally okay, but frequently will have one or two bad out of the box. That's why we recommend the 10 pack so you have a couple of spares.

 

well I kept the old ones but i'm not sure which one was the bad one/ones. I also have 1 brand new one. Guess I should see if there are any codes stored then go from there.
