Yeah it is probably off some but the thing is this has just kind of popped up. It seemed to be fine until a couple of days ago. If you have some pointers on setting them or a real good thread please post it up because I am a noob at tuning.

I don't know...if the filter is getting clogged, under low fuel pressure, it is not getting enough fuel, hence lean. At WOT, there is much more pressure allowing fuel to get thru the filter allowing it to run rich. What about your pressure regulator? I have learned a long time ago, there is nothing logical about our cars ha! I just do not see what spark plugs would have to do with it though?
Regardless, you still have a problem being your band-aid was enriching the mixture which normally you would not have to do. I agree, the A/F mixture guage is a engine savior, in so much as oil pressure and EGT!!!

well if the spark plugs weren't burning the gas correctly I was thinking that it could fool the wideband because of unburnt fuel instead of a lot of spent fuel gasses. I hope that makes sense. I'm really not sure how the O2 reads the exhaust.
