horrible idle

[TalonR]

I couldn't find this anywhere.....but my car is having a horrible idle.....It will sit at about 500 to 600 rpms and it shakes the whole car....My compression is a little below specs in a couple of cylinders, which would make me think valves or rings, but besides the idle the car runs fine......I am getting sick of the shaking so if anyone has any advise it would be greatly appreciated.......Thanks

Check the Biss , turn it up.

Yup, turn up the screw on your throttle body. Should take care of it.

Thanks for the help....I will give it a try tonight......Also the car seems to have a slight miss in it.....I dont know if this would be cause by the rough idle or not......Plugs and wires are newly replaced and it also did it with the old ones....Any comments on that would be appreciated....Thanks
