Now I remember why I've only put 1700 miles on my GN since Aug 2002!!!!!!

This bl# being at 150 is why??Replaced both check valves,vac block gasket and two of the hoses on vacuum block,checked every hose with starter fluid and can find nothing that changes idle.Ran a can of top engine clean thru it and no smoke from anywhere but tailpipes!!!!!!!!!!!!!!Thought to myself "now it's fixed" boy was I wrong,crunk it up bls at 130 then climb to 150 AGAIN!!!!!!!I'm to the conclusion that after I replace the O2, 150 is where it's gonna stay( if the O2 doesn't fix it )until something breaks!!!!!!!!When I parked car in May of 02 everything was fine,bls at 130 and had been a long time.Then it was Aug of 02 before I drove it again and this stupid problem just started!!!!
Now I'm gonna take a pill and chill out,I feel better since venting!!!

This may have been better for the lounge now that I think about it.I guess I was subconciously asking for more ideas to solve problem as I can hear the GN from the carport begging to be fixed.It's just stuck in my head,"FIX ME,FIX ME,BLS TO HIGH"

you sure yo dont have a exhaust leak somewhere, maybe crossover pipe or header. - i know you used top engine cleaner but just a thought. Also if check valves were bad there was probably damage to whatever they were connected to.
