added some redline injector cleaner to my car b/c the injectors seemed to not be closing all the way and it was rich at idle. Also fiddled with the afm adjusment screw to see if I could get th CO dow to spec. does any one know if the afm adjustment screw will affect A/F mix at spped other than idle? my car has no power now...slower than a normally aspirated 5series....lastweek it felt like a 747 taking off...
