reduced engine performance

I am having an intermittent problem where the REP message shows on the dash, and I can feel the car isnt as smooth as it should be. Feels a little lumpy. After a few mins this clears itself and the car drives ok again

Any suggestions on what to look at please? no codes reported in IID

I am wondering if the 4 O2 sensors need replacing. Are there any other main culprits?

Quite a few things to check. Map / MAF, possibly an injector on its way out.
