A3 8L AGN rough idle, stalling
« on: July 31, 2021, 07:18:54 pm »
Hi, I have a 97 A3 that intermittently stalls or runs rough at idle, usually when up to temp. It tends to run rich as well. I've cleared the fault codes as I'm not sure when this was last done, but the engine temp, air temp and 02 sensors all had faults. Is there a good source of detail for testing these (engine temp and IAT) before I source replacements? And does anyone have experience (good/bad) with O2 sensors? There are a number on Amazon and the like at a very reasonable $50NZD
