Message So my on going saga with this misfire is driving me crazy. All of the spark plugs are dry fouled which indicates to me it's running rich. Well, it's probably running rich due to the misfires, but what it also indicates to me is that all of the cylinders are misfiring. This would lead me to believe it's one or more of the follow:

ptu
harness
cas - swapped it out and no change

The misfires happen about once or twice every 5 seconds, but are slight enough for all the cylinders to pass a power balance test.

Any other possibilities?

I'm guessing a vacuum leak would induce a lean misfire and therefore it'd be running lean and the plugs would have no carbon deposits?
