On Friday, when I was driving home from work, the RPMs would drop extremely slowly when trying to shift. I would push the clutch in, shift, and then I would have to wait about 4-5 seconds before the tach would drop enough to match rpms for the shift. When I pulled into my garage, I reved it up a few times to see if I could hear anything out of the ordinary. The throttle body is making a very loud slapping/banging sound when the engine is idling and then I hit the gas. So, I pulled off the intake, thinking that something might be loose in the throttle body, but everything looks like it should. I turned the ignition on (engine is off) and when you hit the gas, the throttle body continues to make that loud bang. Does anyone have any ideas? I'll probably just end up taking it in to the dealer next week. I sure hope that this will be covered under the powertrain warranty!
