Do you have any noticeable drive ability issues? Hesitation or jerking? Have you had any work done recently besides those part replacements?

What engine did you install in? is it the same as yr previous

Was it the 8v or 16v? Reason I'm askin is my cambelt slipped of due the tensioner bolt snapping. So I decided to install a 2ltr 8v and errors just popped up like mad after fitting a dictator management engine works like a dream but my engine light is on due to a few plugs that are not needed.
