Hello all

I have a 1.4 2005 punto in the family which I've been having a go at sorting.
It starts and ticks over fine warm or cold.
The issue is when you blip the throttle the rpms splitter then pick up fine through the range. The same also happens when you pull away. If I'm gentle on the throttle it's better but under hard throttle a lot worse.
Had codes up for both o2 sensors so replaced those and also plugs. Air filter is fine.
All the coil connections seem good.
Steering light sometimes comes on,don't know if that has any bearing on it.
Was wondering if part of the throttle body display g up?
Any help appreciated
