Thanks for the response! What is the reasoning behind using non-resistor spark plugs? And where can I find them...best brand to get...etc?

And as far as the Air Mass Meter, I haven't tried the dollar bill test yet, but the metering plate seems to move freely with uniform resistance, and returns to its original position. If I would push on the plate with the engine running, the idle would get rough, and didn't seem to recover, and if I pushed it harder, the engine would stall.
