Stalls after stopping

[Kevdoo]

I have a 2001 325i with 128,000 miles automatic transmission. When I first started driving there are no issues. However, if I stop at a store and turn off the car, I'll have an occasional slow start and the car will stall when I press the throttle pedal. I've replaced the fuel filter and I have replaced the plugs and ignition coils. Has anyone experienced this issue and what was the diagnosis? Thanks in advance!!

The first step in diagnosing a problem is to scan the car’s computers for codes. The Service Engine Soon light is on only when an emissions related code is present.

Could Be

Crank Shaft Position Sensor

Cam Shaft Position Sensor

IF you get codes for those change them!!!

Sadly, I believe you are throwing good parts and hoping to hit a home run. The good thing is that these parts should be changed eventually, and you may have changed them early. I recommend saving the old coils
as I am certain this is NOT your issue and they are fine and I would keep one in the trunk always.

I cannot tell as I need more information, but it may now time to clean the AIR IDLE CONTROL VALVE below the throttle body. If gets stuck when old and dirty. I would allocate some time and get it out, clean it, lubricate it
and put it in again. I suspect it works, but test it (somehow). It could stick open and allow unregulated air in the engine causing it to crap out. PS: getting to this valvel is ugly, but a great chance to clean the throttle body,
MAF sensor(be careful), and check all crusty vacuum lines sine you are in there.
