Clio 3 1.2 TCe 101hp (p0300 code)

Hi everyone, I'm having a problem with my Renault Clio 3 (petrol engine). When the car gets warm the engine starts to vibrate and idle roughly, and the check engine light starts blinking. I scanned it with OBD2 and got code P0300 (random/multiple misfires). I also captured live data and a freeze frame screenshot while the light was blinking, so I know it reflects the issue in real time. Here's what I've already replaced:

• Spark plugs

• Ignition coil pack and leads

• Engine oil and filters

Cleaned the fuel injectors

New timing kit

• Valve clearance The problem still comes back after warming up. Anyone experienced something similar or know what to check next? Thanks in advance! (Screenshots attached)

Did you fit genuine TCE spark plugs?
Also give your TDC sensor a clean.

yes but is it the correct plugs? 1.2 16v and 1.2 16v TCE are different.

once plugs and coil pack/leads are ruled out id be looking at injectors, thermostat and upstream lambda
