325ix running rough on start up - revving fixes issue

[D.Martijn]

I checked the fuel pressure to the rail, got 3bar. after 1 hour it dropped to 2.5bar
Tried starting it, again poor idle.

After that I cleaned the ICV and also removed the injectors, jumped the fuel pump relay and looked for any leaks on the injectors, couldn't spot anything.
I got everything back together and tried starting the car, it ran fine. However I'm not sure I really solved it or it's just because I didn't let it sit long enough.. I'll have to try and start it some other day to check.

edit: I also checked for any vacuum leaks with a smoke machine, nothing..

I drove a whole day with a couple of stops 2 weeks ago and it necer had this problem. it occurred all of the sudden only when cold/has been sitting for a while

i was also thinking it might be the injectors leaking, causing it to loose fuel pressure. Thus needing to rotate the engine a couple of times till fresh fuel is at the injectors + it running rich the first few seconds because of the injectors leaking

Did it start doing this all of a sudden? Or gradually got worse to this point?
Does it do it every time, or only on either hot or cold starts?

This has some strange similarities to a problem I had - leaky injectors could cause a hard start and then some wonkiness until the engine clears its throat.

Hey guys,

Just recently my m20 developed this issue.
When starting the car, it takes a while to get it running right.

As you can see in the video, it has a hard time getting the idle right.
I have to raise up the rpm to get it to idle. While doing so the engine smells heavy of fuel.

Does anyone have an idea what could be up?
