Error code P1171 and P1172

[nicokoppers]

Hello from Holland dear Maserati friends,

Yesterday the error light of my Maserati 3500 GT was burning.
When I got home I put the OBD meter on and was given the code P1171 and P1172.
Can someone tell me please where those codes stand for? Does anyone know if Maserati OBD codes are published anywhere?

Thanks in advance and best regards.

Off the top of my head in generic terms p1171 and p1172 are fuel trim codes, could be all sorts air leak maybe MAF's ect
