Hi Luuk!
Have a Maserati 3200GT, 2001 manual (58K km).
CEL comes on occasionally without affecting the performance.
Error P0220 (no limp-mode).
After clearing the error, CEL goes off. However, after a few hundred kilometers, it reappears again.
Probably the solution is a contactless throttle body.
Please let me know if you can fix it.
Thanks!
