Hi All,

I'm experiencing low throttle, low RPM hesitation on my n63 x5.

Idle is fine, no error codes.

A search only shows maybe:
- Dirty MAF : How do I test if MAF is dirty, looks clean to me?

- Cabon build up: don't want to use seafoam just yet because I bet ill end up breaking the vacuum hose clip trying to remove it, that hose clip looks brittle.

- Transmission on it's way out

- Coil on it's way out: would an error code come up if it's starting to fail?

- Fuel filter or pump, would that show any codes? anything I can try there?

I've done spark plugs, air filter, pcv already just as part of regular maintenance.

Any thoughts would be good...?
