HI guys...

I have been getting car/spanner light intermittently, used to just come on and off randomly, lately its got a lot worse and now stays on for sometimes hours, and car is in limp as feels very flat to drive..

Pulled the codes and its showing 0220 and 1550, which I believe relate to throttle body errors...

So first I removed it and gave a good clean, still the same, so I changed the entire throttle body, but its still doing it and giving the same 2 errors...
Can anyone suggest what to try next??
thanks.
