Hunting for idle when coasting, VSS related?

I've gone back and looked at lolcantturn and trackjunkie21 videos

As we've fixed things on our cars over the last few weeks, I'm not so sure we're having the same issue...

[Adrian_Visser]

So you don't have this problem?

I have a 3.5 MAF with a cone filter so the theory of those being the cause are out.....

[Adrian_Visser]

Just think aloud again, but it seems that all of us who are having this issue have just a cone filter at the end of the MAF. Not saying that is the issue it's just a bit odd, tis all.

That is an interesting co-incidence, I even get a MAF code because of the placement of my filter, or at least I think that's why, I'm running a 3.5" HFM with matching software. have swapped MAFs to no avail.

For what it's worth I haven't been able to get the stomp test to work since about a week after I got the swap running either. The only way for me to read codes is with the Peake scanner through the diagnostic port.

I've just been driving the mother for a year and enjoying it. It's funny I forget about all the issues until I start writing about it.

Doesn't tell the O2 relay to turn on sooner

Well i haven't checked the o2 relay, I suck lol but I have noticed that my vss signal is getting to the ecu when car is cold, idle raises and drops as it should, once it warms up it starts acting up, hmmm

Guys found the problem? I have the hunting idle when I come to a stop or car is on neutral. It stops after 10sec. though

[trackjunkie21]

trackjunkie, you said you replaced your Crank sensor and Cam sensor since the issue started?

I've tested so many things that I can't remember if I tested those or not. Looking through the wiring diagrams, the Cam sensor seems to give input for a lot of components in the car.

Also, the more I think about it, my car is essentially in "closed loop" for 9 minutes.

yep, cam and crank have both been replaced.

Just to try to throw a little confusion into everyones head.

I am currently swapping an M50NV into my 92 325ic so I don't know how that's going to turn out but i know for sure that I have the exact problem as seen in the video on page 1 in my stock 1995 M3.

Nothing has ever been done to the motor. E36 harness, E36 chassis.

Figure this out and I can fix my E36 and make sure my E30 doesn't do this either.

[trackjunkie21]

manual harness.

[lolcantturn]

Bought an E34 manual harness from 328ijunkie...I'm going to put an end to all of this. If my car has the same problem, well, may god help us all.

[lolcantturn]

Manual harness.

[Beej '86 325es]

Was going to check today but I forgot I did install a new ICV and that did nothing :(

Sorry to hear that...

Those of you with E36 harnesses, was your harness from an auto or manual?

Mine was an auto and I stripped out the wires.
