alright i guess first of all 88 vert s4, RB downpipe and presilencer, and all emissons removed. so now the idle question. after doin all this on my new motor i get the idle set where it sounded good and get inside the car and its idling at 1500 and when i adjusted everything to get it to 750 yah it sounded like **** and basically died. sooo the question is, is i have heard stock rpm gauges suck but how far has anyones been off before i go buy and aftermarket one, and question two is is there a way to tell if your coils and/or igniters are going out? (just having fun like everyone else trying to adjust their idle....)

Get a copy of the factory service manual for your S4 from one of the links in the 2nd gen FAQ at the top of this section. Instructions on how to properly set the idle and how to check the ignitor/coils is in there.
