Default

So if I magically get rid of the misfire by, for example, putting a new spark plug in cylinder 6 will it stay in limp mode? Is it in limp mode now anyways? It Idles just like it should when it's cold but once it warms up it's a little rough. I have a code reader and can clear the code. Should it be cleared after a new plug?

Default Running Lean, whats normal?

I have been chasing a misfire in #6 for a while now so invested in a code reading and software program and it says my banks are running as follows...about 200F at Idle...Short Term 1 is the only bank to change from Lean to Rich during reading, the rest stay at Lean....

Short Term 1 - Lean 1.5% to Rich 0.8%

Short Term 2 - Lean 4.0% to 7.0%

Long Term 1 - Lean 2.3% to 3.9%

Long Term 2 - Lean Stays between 0.0% and 0.8% but will randomly shoot upwards to 5.5%

The plugs(Motorcraft) and wires(Bosch) have less than 1500 miles on them but when I took out the #6 plug it looked like it had 25,000 miles on it. The other five looked how they should-new.

Any help is much appreciated.
