This #$%^&*@ car! long post

[Ross]

The latest for anyone still following. Stumble remains off idle. Intake gaskets not changed becuase no matter how much stuff is sprayed around them there is no change to idle.
A 570 mile road trip on premium fuel with a fair amount of over 3000 rpm running combined with crawling in construction zones delivered >23 mpg and pipes look nice so I'm otherwise happy with state of tune.
Back to suspecting idle control valve. Has anyone here had a similar plight due to IAC? Mine is clean and ohms out nearly identical to a new one.
I hate $100 guesses so am looking for someone who's been there.
It's best described as a stutter, a couple of tiny little hesitations just off idle, more noticeable while driving but still there if just a free rev in neutral. Many wouldn't even notice it.
Who thinks IAC valve?

Did you change it out yet?

Place your hand over the valve when the car is running. Do you feel the valve "stutter"?

Wow. How did this get resurrected?
No. I never changed the idle valve and spraying all sorts of combustible things everyhwere a vacuum leak could be netted nothing.
The car has been parked since the GF has taken a liking to the E39. While some ding repairs were being done last summer the battery got run down with the doors open most of the day and the dent man listening to the radio. This effectively performed a computer reset and when I took it around the block a few times all seemed well. Perhaps it needed to unlearn all the bad values aquired before all the other work was done.
I need to give a little exercise nd see if it's really fixed.
Wasn't it me who started a thread about following up a while back? Sorry guys.
This car is surplus now and I really ought to dispose of it as sitting in the diveway for months on end isn't doing it any good.
Anyone who want a touring let me know. The front bumper cover has been replaced for anyone following this cars posts.

Only an idle thought,buy a can of ethyl/Easy-start and get spraying.You swear there is no air leak but it seems one of the only things left! Revs go up there it is.
