308 (2016) Engine shaking with black liquid come from exhaust

[Awnish]

Hello every body

I have 308 t9 2016 with a 1.2 i THP 130 purtech petrol engine.

Previously, my engine went to shake really bad making engine turn off by it self two times before, but later this not happen. These days I still get some minor shakes while waiting behind red lights . Later, I notice when engine is on and the car is stop and the engine start shaking there are some white smoke and some black liquid come from exhaust,Has any of you experianced such a thing?

The shaking could be bad spark plugs, a timing problem, or several other things.

Do you see a lot of white smoke, or just a little?

The black liquid...is it thick or thin...how does it smell?

Doe you have any fault codes?

No fault codes , recently I solve “service” issues related to self ignition by DIY air intake valve cleaning.
For timing belt and spark plug , I change them 1 month ago
The white smokes are little while shaking only.
Black liquid is thin , i didn't smell , but feel it as water.
