Let me explain all that they did.
1. Dme emmision recall... This may be part of the solution.
2. Showed me a borscope pic of 3 ports, man it was baked on there.
Never been cleaned before.
Dealer did the walnut blasting.

So, day 4.5 driving.
I have seen approx 90% of jerking issue fixed.
When shutting car off for 5min or more then driving.
I can feel it still felt it jerking.

I think the current jerking is very minimal.

Fuel economy is better by from 13.8 to 11.7-9 l/100 km.

Next think I try is BG 44K.
Then spark plugs, oil change.
And maybe all 6 coils.

Let you know.

Can almost guarantee you it's the plugs that are the remainder of your problem.
Those things probably got fouled or burned by the improper air/fuel mixtures over time.
