Running Lean

Really lean actually. Replaced all vaccum lines, checked tightness of both upper and lower intake, changed fuel filter. Still runs lean though. Anybody got any ideas?

If you have a Haynes manual it has instructions on page 4-22. It sounds like there are a couple of voltage checks that can be done. If you don't have one I will try to come up with a summary for you.
