2002 explorer 4.0l sohc

[Nationally813]

Recently my explorer has a rough idle it's been fluctuating on its own and will die if gas is not pressed. Check engine light is on and it's starting 02 sensor too lean, just replaced the iac valve and still rough idle. I don't know where the vacuum hoses are located. Please help me going crazy and I just cleaned the throttle bodyas well. PPlease any suggestions!!!!!

Start by testing the battery. Does it start on its own? Do you have to jump it?

Lean means lean. When's the last time u changed the Fuel Filter?

Huh? Faulty battery for lean codes? :scratch: What were the trouble code numbers?
