shakey acceleration

[rsalomon13]

Let me know if you find an answer to this. My 07 STI has jerky acceleration/hesitation under 1/2 - 3/4 throttle. In my case I am 100% sure it is not the clutch. I will have to look into the 02 sensor path.

Its probally just the crappy tune on the 07's. Most of them from the factory have this. Fix it with a tune or I believe the dealer has a better map, but its still crap.
