Megane IV check ignition and anti-pollution system

[rollingstone321]

Hi renault fans,

The check injection warning has come up on my megane IV (2019, 1.3 tce) and I have a loss of power until 4000 revs.
Car has done 140 000 km (86 000 miles), and I was to get an oil change at 150 000 km (last one was at 120 000) and also change the spark plugs.

What could be the problem? too old spark plugs? polluted gasoline (I have topped up my tank last week with a jerry can)?
What to check and do first before going the expensive route.

Thanks

Foutcode is uitgelezen en is P1453. Wat wel raar is want deze komt meestal alleen voor bij diesel motoren. Iemand die raad weet?
