yet another Idle question
- I have an 87 535is. I recently had a question about a vacuum hose
routing diagram, which I resolved when i was able to actually look
under the hood of another 535i. Now I have a question about the idle.
I have a little bump in the RPM (almost like a miss, but not as
pronounced and consistent). I think it may be caused by a hole in the
exhaust in front of the catalytic converter, which I discovered when
inspecting the exhaust. Is this a possibility? All of my vacuum is
solid (including new injector seals), and ICV, etc are fine. It is the
only thing I have not addressed.
