When on part throttle, accelerating from a junction, it doesn't accelerate smoothly. It doesn't 'jerk' (like me), it accelerates, then drops slightly, then back to normal, then holds back again, then goes, then holds back. Alternating every second or so.
On full throttle, it's fine.
You can see the MPG meter moving down slightly, then back, then down then back, in synchronisation with the feeling of holding back.
I was thinking possible O2 sensor?
Any other ideas? It's fu**ing annoying.
