i got a 96 a4 2.8 5 speed quattro its idling a little rough, no CEL the only thing that pops up when you start it is IN1n2

ANY ideas? it sounds like it might have an exhaust leak too but i dont think that would cause this problem

 

Clean the MAF and replace your air filter if you haven't recently. Start simple. You might also wanna check yer plugs.
