Hi @Raddy (& welcome)!

Can you give us some more details on your car, which engine etc? Someone with some technical knowledge will be along soon, and they are bound to ask... ;)

You need to get the engine fault codes read to be sure, but could be simple such as blocked air filter, crankcase breather, split intake hose etc or alternatively it could be more complicated like a sensor (cam, crank, lambda etc) or throttle body issue, reading the fault codes is the best bet, no codes means something simple, new air filter, breather etc (good service) or if you get a code then you will be on your way to another more specific answer.

Sorry i cannot be more specific for you

Those readings would suggest to me a car which running at ideal levels ie a car in fantastic engine condition. I think Zedonist is on the right track, get it code read and see what it shows. Where are you , if you're any where near me in Lincoln I could help. I wouldn't worry unduly. cheers Tony.
