Lean bank one lean bank two....grrr

[clintons4]

My car is running fine but I have this same code again (lean bank one and two) I have looked it over. There are no vacuum leaks to be found. I need to get this fixed to pass inspection. Any help would be great.:help:

Check the spark plug gap. Solved my issues.

There seems to be unmetered air coming from somewhere or poor fuel distribution.

I'm still betting on the MAF sensor elements(wires) being dirty... When they build up a film, the sensor element is insulated and tricks the PCM into thinking less air is entering the engine... Result is reduced injector pulse-width causing lean code(s)... I've fixed at least a dozen different Fords by only cleaning the MAF, latest was a '00 Explorer just three days ago...

smoke test it and if there's a leak it will show up..........go from there.....

Ok. Looks like I will have a chance today to clean the maf and reset the code. If its the intake gaskets, I may as well get my Camaro SS inspected and start the eaton swap. :D

Do you think an old fuel filter could cause this? I don't have any way to smoke it so I would like to try other routes before I have to pay someone.

If cleaning the MAF fixes it you'll likely find it feels like you just gave it a fresh tuneup...

The '00 Explorer I just cleaned probably picked up 10-15Hp, has lots more pep and AFAIK it's running it's original 117Kmi spark plugs...
