Yeah these engines seem to be difficult to diagnose once something goes wrong. So you spent a ton of money on the throttle actuator and you still ended up having a only slightly more stable idle. Looks like i will probably just live with it. The car still has plenty of power. i just ran 13.636@105 and could have ran better, so im not losing any of my performance.

The only thing that really annoys me is what feels like constant shifting when going down a hill or when im doing less than 50kmh. But when I slam the accelerator down she still moves!
