I have a similar problem. I have had the car for about three months, and has most of the stage two done to it. And this has been happening the whole time and i cannot fine out what it is.

Ok, the CEL goes on, the car seems fine. It is fine when it is cold or warming up. But when I drive at a constant speed(engine hot), every once in a while my engine has a constant misfire and the A/F gauge is pegged to lean. It will do this until: A)I turn off the engine during driving, B)If i put the stick in neutral(or press the clutch) for a certain amount of time, or C) I clear the misfire cod. Now, as a side note my speedo stopped working for about a week(until i fixed it) and during that time no code showed up and the problem was gone. And it seems the faster constant speed i go the more frequent it does this. Oh yeah, once the CEL goes on it stays on until cleared, it is just the actual misfire that comes and goes. When it is gone the car runs awsome.

I have no idea what this problem can be.

This is the exact same thing my car started doing the other day. I put it in the garage and grabbed the bike for now until I get time to test it. I plan on testing the plug wires and coil pack. Maybe someone else can chime in with other ideas.
