Ok so for the first time since owning my s3 i decided that i would give it a little stick.. So i put my foot down and let the revs travel at about 5k revs the engine seemed to die as if there is a rev limiter. the car jolted and would not go any faster. I let my dad take it for a spin and it did the same thing. But he put his foot down a second time and it didn't do it any more.... Although the revs when they hit about 5-6k, the needle looks very bouncy the dial does not move as smoothly as it does on the way up to 5k revs. What could cause this problem has anyone had this problem before? The s3 is on 70k miles 07 plate its mint other than this. Has warranty also NOTE: I installed a Forge DV spacer just before i found this problem never had the car at 5k revs before hand so would not know if it did it before. Tonight i took the Forge spacer off and it still does it.
