Had several codes and repaced front passenger O2 and was able to get rid of a couple of them. I am still getting p0302 and P1176, P1177. I installed a brand new coil pack on cylinder #2 and that did not help. I installed a new ICU and that didn't fix it either. I swapped the spark plugs in the 1 & 2 cylinder and still getting a #2 misfire. Now I occasionally get a #1 misfire too. I have no idea what the problem is any more. Anyone help? If not anyone know a good shop in the Northeast Atlanta area?

 

BTW the previous owner installed Denso Iridium's just before i purchased. Anyone else running these kind of plugs?

 

Hi,

Why don't you get the enigine checked by a Audi dealer?

 

Becase i have a Vag-Com and i don't know what else to check for on my own.

 

P1176/7 = INTAKE LEAK so check all the vacuum lines/ air leak at #2 injector,

P1176 = lambda correction after catalyst, bank 1 control limit reached.

P1177 as above but bank 2
