Hi

Got a problem with my ST220 its a 55 plate

Starts and drives ok but won't go above 3000 rpm, The AA had to recover the car as it was stuck on the M1
Fault codes showed up P0133 P0153 P0171 P0174 P1131 AND P1151
Fault codes reset and only 2 remained P0171 and P0174 banks 1&2 running lean

Has anyone one had this issues resolved or any idea's
Have done lots of searches without any success
Revs ok in neutral problems start when driving and get worse when the engine is warmed up

Help greatly appreciated
