85 turbo needs YOUR help!

The proble is with my second car, a 1985 740 Turbo. Car idles rough, and the idle speed varys by as much as 350 rpm sometimes, for no apparent reason. Its not getting enough of someting (air or fuel), and then its getting plenty of it, and then not enough again. The whole engine shakes around alot, and just generally runs rough. I have looked for a vacum leak, and checked the plugs. Sometimes the car will just die, usually right after startup. I would REALLY appreciate it if ya'll would gimme a hand here.

Thanks!

can you say..... MAITNENCE FORUM! try cleaning Throttle body

Definately take off the throttle body, clean it, and clean out the idle bypass, and then get back to us.

Jose, this is the maintenance forum.

I will clean the TB and let ya know what happens. Thanks.

OK I pulled the hose off tha TB and it didn't seem really dirty. I'll clean it anyway, but the purpose of this post is to discover WTF an idle bypass is?
