Hey Scotty I have a 2001 Toyota Corolla CE with the check engine light on. I have replaced everything the codes are coming up and i still cannot get it to pass emission. i have replace spark plugs and coil packs and maf sensors twice, pcv valve change the computer and i am still getting lean bank codes, what else can i do please help and i have had this done at the shop where they ran the diagnostic test.

lean is often leaking intake manifold gaskets or dirty worn out fuel injectors
