My 02 3.0 is running bad, almost sounds like it's missing firing or not running on one cylinder and it back fires quite a bit. I've replaced the spark plugs wires fuel filter IAC and the downstream o2 sensor. The fuel pumps working fine and I'm at a loss. It's throwing a code but can't read it due to the previous owner deciding the normal plug in for the code reader was for loser and putting in a USB. I'm in the process of replacing the upper o2 sensor but one won't come out. Any help is welcome I'm just at a loss of what to do.
