I have an 89 325i that starts to idle rough when it gets warm. It was previously idling poorly all the time, a cracked breather hose cured most of it.
When it warms up, it's like a light switch, all of the sudden, the idle drops to around 500rpm and it gets very rough.
I've searched for about 2 hours but I don't think I've found what I'm looking for. I will double check vacuum leaks, test the fuel pressure (I've seen a few where fuel pressue regulators have come up), and maybe try adjusting the idle if possible.
Any other ideas?
Another problem it has is the engine will completely shut off for a split second, and the check engine light flashes for the split second that it's happening, but it turns right back off and the car continues to run fine otherwise. I noticed it doing it under hard acceleration, but now it's doing it at low rpm light load situations as well.

The ICV moves freely. It's more of a misfire at idle once it warms up, and continues as I accelerate to about 1500 rpm, then goes away.

The car keeps throwing a code for the coolant temp sensor. The temp sensor is new, tests good, and the wiring checks out. I'm done working on this POS.
>ooo its your timing, your car doesn't have the motronic right? if you dont know how to time it then take too long he would prolly do it while you wait and then that should take care of it.
That post makes no sense at all. Who is "he"?

Now that so called BMW shops can't seem to figure it out, I'm back at it.
Here's the latest symptom. The car misfires when it's warm, and it's like the ignition is turning on and off sometimes.
Is there some sort of main relay or something that might need replacement?
