TPS/vanos are originally. Last valve adjustment was probably 40k ago. I was planning on doing the vanos and valve adjustment in the next coming months. Iíve been knocking out all the big stuff recently. Subframe/ rod bearings, and other relevant maintenance.

I went ahead and did plugs and my coilpacks are all original. I may replace all of them to see if that helps at all. I figured if there was a going coilpack, it would throw some sort of code for a misfire.

My first ever infamous post on m3forum last Aug was chasing bogging and misfires (with no codes). Valve adjustment I would say helped the most, outside of some moisture in gas tank.

Get valve adjustment and vanos done. Vanos seals refresh can also help a lot with feeling loss of power. Outside of those 2, you can try to get a TPS above the oil filter from a well running car to see what happens, they result in weird throttle cut out issues. Maybe yours is on the way out, at the least check the connection on it is snug.

Iím going to give all of these a shot, Iíll start with coilpacks, valve adjustment, then to the vanos. Another interesting Iíve noticed:

After my original fuel pump died, I replaced it with the walboro/radium kit. Even after adjusting the pump in the sleeve. I could never get the car to run to NEAR empty without it starving. I replaced it with an oem pump a few weeks ago. And today Iíve noticed that around a quarter tank this one starts fuel starving as well.. any ideas on that?

It sounds like maybe it's installed too high/improperly or the float is malfunctioning.

With the previous walboro set up, I adjusted it to sit as low as possible.
With the new oem pump and brand new housing, itís occurring again. So if itís not an issue with the install/housing. Is there another sender that could be faulty.

Guessing the one on the passenger side, looking at these threads:
