Well I changed out the O2 sensor and no change. It drove great yesterday, but today it was the devils child.

At WOT it just bogs down and then chugs hard back and forth. If I let off on the throttle, it goes back to somewhat normal driveability. As long as I don't put my foot more than 1/3 of the way into it I can drive around. The wierd part is I'm not getting a CE light consistently. Sometimes I do, then it goes away once I keep my foot out of it.

My biggest concern is if I am in a situation where I need to get up and go, this car will do the opposite and almost come to a stop.

To date I've changed the MAS, 02 sensor and plugs. I had another issue in which when I changed the MAS I could then start the car without it stalling.

Is there anymore DIY items I can do before I surcome to the mercy of the Dealership?
