The engine revs for about a second (feels like the clutch isn't engaged) and then the car will then "catch" and jump forward. The clutch isn't stiff or clunky and this doesn't seem to happen in lower gears.

Ideas? I hesitate to take it to the local dealership because they're extremely shady and have needlessly cost me money in the past. Hoping this isn't a major fix?

I bought the car in August of 09 so it should still be under warranty, right?

Thanks folks.

If you do not experience this in lower gears (1st,2nd,3rd) than your clutch is fine. This car is a drive by wire throttle body. The lower the rpm's the more lag you will have. If it grabs hard in the lower gears you have a different probelm

He makes it sound like the lag is pretty significant. Drive by wire or not, he's still in a manual tranny car and it should be rather responsive.

The throttle is controlled electronically, No Wire Cable is used like in older models
