Checked out my spark plugs for being dirty/fouled from running rich for the past year. When I got to no. 3 it was finger loose! Tip looked decent light brown color. This was my own poor tightening work.

Yes, indeed my MPG is back to 17 city 23.5 highway, for LH 2.2 turbo that's good people.

So between the intake manifold gasket leak and spark plug air leak was the problem. Everything else wasn't likely necessary. Dang these vacuum leaks!

By the way, the spark plugs are Denso iridium power plugs, and they run fantastic in my car.
