I've got a CEL for O2 sensors not working and we've already swapped both upstream sensors with brand new Motorcraft ones.. light went out for about 5 minutes and the engine got super quiet.. light came back on and the engine got loud again.
The shop told me to take it back, which I shall but right now I'm waiting on some parts to arrive from Bill Jenkins before it goes back..
As far as the misfiring and idle problem, I'd like to get that taken care of before as I need to drive it to the shop.. I'm going to swap the coil pack later after work tonight for 5hits and giggles.. if that doesn't fix it then I think its time to test the fuel pressure.
Shoot, I drove my 2.5L with a misfire all day long for months!
I couldn't fig out the problem, but I had no other choice. To be honest...I never really fig'd out what was causing it!
WHen I put the 3L in I used the same wires, but a new coil and new champion platium plugs.
