1M Misfire

Hello Everyone

Wondering if anyone can help to with a misfire/stumble transitioning through 2400 RPM @ open throttle on my 1m. No codes. get 2-3 stutters and keeps accelerating. Cars done 45000km (28000mi) no mods, factory tune. 98RON fuel

The fault is intermittent as well. I've changed plugs and coils to start with. My service shop suggests injectors next. But I'd like to avoid change bit and hope solution if possible.

Reading the forums usual suspects for faults people seem to throw injectors, carbon cleans, LP and HP fuel pumps.

thanks
