They've had my car for over two weeks now. They put in a new O2 sensor, but that was not the problem. There's three mechanics on it now, plus Tech Line, all scratching their heads. The next step is to order a new ECM, because the current one is telling cylinders 1 & 3 to run rich, and something is overcompensating for something else and blah blah blah. At least that part is covered under warranty. So I'm picking up the car, since it'll be another week before the ECM gets here.
The plug with the most carbon is the driver's side plug at the front of the car. Cylinder two has no misfires. I don't know if these are the same or not.
Don't know anyone with Tactrix cable or that can datalog. Don't have my car either :-(. I'll try to get a better pic of the plugs.
