I have 98 ls1 A4 drivetrain and my idle appears to be off. it variates about 100-150 rpms up and down and idles high in general. Sometimes it will idle right around 550 with out any variation tho. I logged some data with hp tuners and wondering if by looking at it anybody can tell me what is the most probable reason for the idle. The log includes a lot of idling in the beginning and WOT run in the middle with some highway speeds.
