2017 Tahoe with very rough idle
We have a 2017 tahoe with 155K miles on it. It began idling very rough a few weeks ago. It had bank 2 sensor 1 O2 sensor bad so I replaced it. Still not better. I ended up replacing all the spark plugs and wires. No change. Cleaned the MAS air sensor. No change. 3 mechanics have looked at it...- dksharp
