I've aleo checked the injectors and they seem ok,

it's also just had a cambelt, depasher pulley, water pump, coolant, oil filter and oil change. The engine is in around 107k, any ideas guys it's driving me mad all I want to do is drive it

Start with CLIP, run the misfire detection program and see which cylinder has its knickers in a twist first off. Then go from there.

What do you mean by the clip? I'll get a diagnostic done and see what's up

CLIP is renault's diagnostic software. If you've replaced everything else it's probably going to be an injector even if they look ok. Mine has gone through 2 in 9 months. Similar mileage to you at 104k and no evidence that they'd ever been replaced in the past. You can pick genuine ones up on eBay for ~£21 though so a pretty cheap fix.

Agreed - I've not even seen the car and i'm pretty certain it'll be an injector causing a 10-25% misfire rate.

Just bang x4 brand new units in and be done with it

Good spot. No marks in their ebay pictures but the marks are on the connectors of the 2 injectors I've bought so I'm happy they're genuine.
