i have a 99 prelude and it seems to idle kind of rough.... the idle stays still at about 7 or 800 rpms, but i get a lot of vibration on the steering wheel and inside the car etc..... is this normal for the 5th gen ludes or is there some way I can fix it.....a couple other people have complained about this on their ludes and we are still trying to figure out how it can be solved.......any insight will be helpful
