Hi All

well get this. I have been thru various replacement and tuning expenses
trying to solve performance problems. replaced muffler, O2 sensor, fuel
filter, valve adjustment and lots of head scratching..... The good news is
that I needed all those parts anyway but in the end it was the nut/cap for
the CO test port on my exhaust system which is right before the catalytic
converter. It seems this rusted and leaking slightly. my van was making more
noise during acceleration but no noticeable difference at idle..... finally
on a test ride up to lake tahoe the top of the cap blew off..... I just
replaced it and now the van is runnning great. I figure a slight amount of
air was getting into the system and causing the 02 sensor to richen the
mixture.......

Duh!!!!!! I guess my troubleshooting skills could be better,

thanks to all those that offered help on the list

Ed :-)
