Had this 2003 ranger for just under a year now, and the check engine light has started coming on. A code scanner gives two codes - Bank 1 lean, bank 2 lean. I also noticed that the misfire count went up by 1 when the code went to pending, and then went to 2 when the code went active, and at the same time there was a fairly loud ticking sound coming from the engine.
The freeze frame data said that the fuel mix was at 99% when the code was triggered, this is almost always at about 5% when I just look at it with the data feed.
Tried running 91 octane no-ethanol/oxy gasoline and clearing the codes, the problem came back in two drive cycles.
Looked carefully under the hood and noticed all of the spark plug wires going to the right side of the engine were touching each other, and the insulation had mostly worn off the parts that were touching.
Unplugged all the wires and routed them so they didn't touch each other anymore - the ticking sound was gone. The check engine light came back on a week later with the same bank 1 bank 2 lean code and showing a misfire on the misfire counter.
What are the possiblities that new spark plug wires could fix this? It seems somwhat random and always related to a cylinder misfire.
