i noticed today that while sitting at a red light the idle was a little jumpy not much and it doesnt always happen maybe 100 rpms or so.jeff any ideas other than that car runs great.

Could be the computer having an issue with getting a good a/f mixture... dirty injectors or other. Otherwise, if it aint broke dont fix it LOL
