I've noticed a vibration at idle with the car in drive. It idles around 600 rpm and is pretty steady. No vib with the car in neutral and if I give it a little more rpm, it goes away. I have a invidia exhaust....Its their a way to increase rpm at idle? It seems like 50 more rpm would do the trick.

Thanks

 

I have the same problem with Straight Pipes and the AC on, my whole car shakes! i think its just the idle spot, I'm going to take to the dealer to see if an ECU upgrade can fix it.
