E30 M42 specific manifold removal for ICV access DIY?

[smbstyle]

So I am wanting to clean out the ICV per some of the DIY's I've found, as I notice a little bit of RPM hunting during warm start-up for the first few seconds (cold start is just fine).

Only thing I noticed was none of the DIY's I have found are specific to the E30 M42, and cant find any specific details on accessing the ICV. I have located the ICV itself between the upper intake manifold and the firewall, but wanting to know the best/easiest way to access it. I am assuming removal of the upper intake manifold, and if that is the case, is there any DIY out there for upper intake manifold removal, or any specific tips and tricks that I need to know before digging in?

Thanks,

-Scott

Ah yes, the previous owner told me about this and included some of the hoses I need to do this. I'll admit it's a little intimidating, and the threads that I can find on this (at least one of the good ones on M42club) is a dead link http://www.m42club.com/forums/showthread.php?t=2742 and it looks like Simon's post is missing a bunch of good photos: http://www.r3vlimited.com/board/showthread.php?t=225616 .

there really IS no digging to find the M42 ICV, very easy to remove:

Thanks so much! Looks like it can be accessed without removing the upper intake manifold.

Don't be intimidated. I was a bit when I got into it but it was a pretty easy job. Make sure you do plenty of reading. I would suggest printing out a copy of the line routeing or having an ipad handy with it available. You can't get anywhere until you replace all the vacuum lines etc.

You may notice a massive difference right off the bat. My car was a 100% difference after I changed out all the lines.

So I was just forced to do this... as I noticed one of the coolant hoses going to the TB was leaking bad!

You're right, as I began taking hoses off, it all made sense. The most simple thing for me to see was just the routing of what needs to be left or added, rather than what was currently there.
