Not sure why the idea is to jump to replacing the TB. TB issues will throw codes. Typically, so will ICV but a sticking ICV won't always throw codes. And is much more likely to cause weak idle. Low throttle input are also handled by the ICV on the M54 engine.

IMO the first step here should be smoke testing it, and if it passed a smoke test I would remove the ICV, verify correct operation and reinstall it ensuring it is oriented correctly.

With the engine running, use a screwdriver 🪛 handle as a hammer on MAF at plug and see if it stumbles.

Don't hit the MAF with a screwdriver (why would anyone even do this?) and don't unplug the MAF with the car running

If you suspect a vaccuum leak you can unplug the MAF with the engine off and start it. If it performs better, you have a vaccuum leak and you should get it smoked tested.

Because a bad film will show up as a stumble and hitting it doesn't mean beat the shit out of it either....

Common sense.
