@hliasmoust12265 if you scan your OBD II, what exact error code do you get? "Check Injection" is just way too broad to do anything with it.

@hliasmoust12265 so this only happens when you go uphill? does that mean anytime your Renault has to work hard, you get a "Check Injection" error?

Sounds like either your injector pumps are starting to go bad or it could be reading bad injector codes because your breather filter needs to be changed.

I had the same problem, and checked it with ODB which said to "change the petrol heating sensor"

  1. Changed and the problem continued.

# I fuel it with High Efficiency petrol 2 times, and got better.

# Then I fuel it with 85% petrol and 15% benzine ( hoping to "clean" the injectors) and got better results.

Anyway it's an old car, but I think is better to check and if it need, change the injectors.
