Is this an air/oil separator problem
I've been experiencing a SLIGHTLY bumpy idle, like +/-50RPM. Cleaned the throttle body, no change. I disconnected the hose here and found a little coating of nice, fresh smelling Royal Purple. RP has a really distinctive smell.
Is this a sign of impending AOS failure? http://i2.photobucket.com/albums/y37...oxster/aos.jpg |

if the membrane in the aos is bad, you will see a LOT of oil at the throttle body / aos coupling. |
I've also been experiencing a rough idle. Getting a P0507 message. Cleaned out the throttle valve but it seems ok. Checked that tube that is in the diagram, and that seemed ok. I think there is an air intake leak somewhere. What is the best way to do it. I know you can shoot some gas in there like:
ethyl carbcleaner I also heard some people can get really hurt in case of an ignition. What is the best procedure for doing this yourself? (i.e. which product is most reliable and more safe) I also don't really know where to spray it. On top of engine? Bottom? Any place in particular that is a common point of leaking? Will there be a noticeable increase in rpm or do you have to listen really carefully? If somebody could show me in a diagram, that would be loads of help. |
With the engine running, spray carb cleaner around all intake joints aft of the throttle body. Check every joint, all the way to the head (for all you swabbies thats not the bathroom :D ) until you hear the idle stabilize . What your doing is temporarily sealing the air leak and I wouldn't worry about an explosion but you just might get a clean engine out of the deal.

It usually stabilizes after it gets going for 5 seconds. It's just on initial startup when this happens. After startup, it will stay anywhere from 800-1000 rpms. Maybe I'm crazy, but it also seems like when I turn the steering wheel, it messes with the rpms while at idle. Are those two systems in anyway related?

The power steering will cause your RPMs to fluctuate when you turn the steering wheel at idle.
