08 MS3 Rough Idle?!
+20-24.80 STFT’s, AFR bouncing around between high 13’s to low 17’s. Vacuum at Idle is -4’s.
Found a couple small vacuum leaks, including MAF sensor oring was broken. 1 revision in from Freektune, trying to get the issue lined out, any ideas? Justin emailed and said it was a faulty VVT. Which was brand new had less then 1K miles, so I replaced it all again anyways, using timing tool so timing is good, and have the same exact issue.
There’s a log posted.
