The v6 Have only one fuel line. Intermittent faults are sometimes hard to find.
On the v6 the fuel pump tends to go at high km, this usually goes hand in hand with hard starting. Auto or manual?
Blocked fuel filter?
Connections on oxygen sensor fine? Damaged during installation of free flow.
Good start will be to run a diagnostics with a dealer.
