Easy one...No mods I'm one that keeps things pretty stock with engines.

Never feel the misfires. I can see them in durametric but that's it.

I would call idle lumpy. It isn't hunting like what happens on lawn mower engines.

Here is the weird thing. When the car is cold at startup the SAI turns on as it should. During this time that the SAI is on there are NO misfires. Which indicates an air leak to me but I would expect to see misfires on more then just bank 1.

I need to pick up a better vac gauge. The only thing I have right now is the gauge on a mity vac which I dont think is all that good or accurate.
