RE: cams & idle

["Joe Doty" <rocco2nr@hotmail.com>]

Just to add my experience, I believe I had an exhaust leak sending false 
signals to my O2 sensor which caused my bad idle.  It idle okay until I put 
in "dual exhaust cam" job, which basically made it not idle for crap.  I 
patched up the leaks and now it idles great.
