Culprits there could be the fuel pressure regulator, or the AMM, or maybe even the idle air control valve (IACV) though unlikely... Ithink the codes are related to air/fuel mixture.

See FAQ for codes.

Seeing as you have the B234f engine, PLEASE inquire about all the timing issues and weaknesses before you need a head rebuild. See FAQ and do internet research.

Good luck,
