1 Poor idling and low RPM power returns... Fri May 22, 2009 1:39 pm

My problem is back. Poor idle and missing at low RPM (low power).
Originally I thought I had a bad spark plug. Swapped them out one by one until it ran better when I replaced one of the plugs. I think it was #2.
Then the problem came back.
So I decided perhaps I have a clogged injector. I ran a half bottle of BMW Group Fuel System Cleaner through it over 500 miles or so. That seemed to help.
Then the problem came back.
Now I am back to my original idea of having a bad coil.
The spark plug wires look old. The insulation shows wear from rubbing, especially near where the wires pass through the cylinder head "hole" in front of my left toe.
New non-BMW wires are $100 or so from my dealer.
What I was wondering is if anyone knows if the ends unscrew (like some of the older BMW automobile wires do). That way I could pick up some high quality new spark plug wire and make my own wires using the old ends and boots...and save a few dollars.
Any comments?
Thanks!
