[QUOTE="huskar3399, post: 665303, member: 25472"] ICV controls the idling. DISA controls your low end performance. but you had checked both to be in good state and now i wonder what else to check. i had the same experience as yours, car vibrates badly not only during idling but also at low speed. there was once when i started moving to cross a T junction, the engine was badly shaking and it went off and i had to restart the car. this happened several times to me. but after i cleaned the ICV, the problem just disappeared. during cleaning the ICV did you try wiggle it and see whether the tiny flap/valve playing? because good ICV should have the flap playing. for DISA did you glue it back to when you reinstalled it?
