Yes, the voltage values seemed to rise when the throttle is opened as expected...Although I did notice that when I let go of the throttle, the value jumped pretty high, then settled back to where it should be...not sure if that's normal or not.

Also, I'm quite sure the head gasket is fine...since I have had LOTS of BHG experience with my 3rd Gen Toyota Supra turbo...which also has an inline 6 and blows head gaskets pretty much constantly LOL. This car shows absolutely no signs of a blown head gasket...and I've smelled coolant being burned before, this car is making a different smell entirely, I'm assuming it's unburned fuel. Plus, coolant won't foul plugs...in fact, it usually steam cleans the cylinder it's been leaking into...so I'm pretty sure that isn't the problem.

The CEL is still lit tho, which means there HAS to be a problem with the Air Mass Meter...unless the ECU is really the culprit, but I'm assuming that they don't go bad too often?

Does the manual say anything else at all about the Air meter? Thanks!

edit: I should also add that I was looking at the old plugs I pulled out of the motor earlier, and they look like they have a hard grey coating on them that I can chip off with my fingernail...only on one side of the electrode...the other side is much cleaner...they are all like this. I'm guessing this is carbon fouling?

I have also noticed that after just 300 miles of driving, the car is starting to become progressively more difficult to start. I'm guessing this means that the plugs are starting to foul?
