Hi everyone I own a 2007 2.5ltr hawkeye and have had some power issues with the car it seems to be between 2500 and 3000rpm in ever gear I get a serious jerking motion with no power but as soon as it reaches 3000rpm it boosts fine (done a smoke test and only leak was through air box clip that is broken) does anyone know what could be wrong any ideas are welcome and appreciated.

could be your MAF - that operates lower in the rev range until the MAP takes over

 

Any error codes??

Sorry it's been a few days for me to reply been super busy the past few days but thank you very much for the help because it was the maf sensor new one is on and the car has never felt better🎉🎉

Glad to here it was an easy fix 👍
