running lean
hey guys, i have a question about my 2.2.
i have a wideband installed in my car. when i installed it, the gauge showed it was running perfect. 13 at idle and cruise, 12 at wot.
after a few months, the gauge was starting to get erratic, 15-13 at idle and cruise, and never 12 at wot, just go 20 (lean)
now it just always runs lean (90%) of the time. when i am just cruising and feathering the throttle it will try to run proper, put it still goes everywhere. give it just a little bit of gas it leans right out
things i've changed.
changed ait sensor (did help a little)
changed ait grommet
fixed exhaust leak (which was leaking before the gauge starting acting up.
seafoamed intake and ran fuel injector cleaner
next im going to try a fuel filter. mine is only 1 year old, but water might of plugged it up.
any other ideas

fuel filter or pump have got to be the issue I think.

I believe he thinks you're talking about your fuel pump
