If a walnut blast hasn't been done, it's highly recommended. It could be the carbon build up causing the hesitation/stuttering
Inspect the plugs properly for injector leaks first
Any logs? |

Here's 2 logs, take a look at the afr for bank 1 and 2. Both logs are just of me cruising, bank 2 seems to be worse than bank 1
