Chronic chugging!
98 4.0L that constantly runs horrible anf gets horrible gas mileage... the check engine light is on and when I check the code it says "system to lean" "bank 1" "bank 2" "cylinder four not firing"....I have replaced the oxygen sensors, all 3, replaced the MAS and spark plugs/wires... but the problem persist...what is going on?

I have my own theory on this... and did a google search on this, as I have been having a similar problem and had those codes a while back...
I have also heard of a fuel pump that has/is going bad causing this problem.... might be worth checking into... I'm gonna try it later next week after I get moved into my new house... If you get to it before I do, lemme know how it goes.
