That's not true Happy. The M54 is a silky smooth engine. But getting it there... well yeah, you hit the headliners. DISA, MAF, vac lines (and gaskets, intake, boots, VC, etc), o2 sensors, VANOS, coils and plugs. I haven't seen many fueling issues with the m54 so I skip injectors and FPR unless something indicates an issue there.

I don't mess around with the above. When I buy an M54 with > 120,000 miles all of those things get done. Only way to own a smooth M54 at the age they are currently. I just did the same with our N52... people have the same complaints about those engines.

Sometimes you just have to bite the bullet.

EDIT: BTW, I am excluding yours as it is a special case scenario, not many like your M54 running around out there. You might have to live with a slightly less than smooth M54. But it makes up for it with smiles and power I'm sure.
