    Hello everyone,

    My 3VZ is rough at idle and stalls. I changed the AFM, timing is good, no vacuum leaks...and it didn't fix the issue.
    Any ideas as to where I might look first?

    As always, help is much appreciated.

    Check your air intake hoses coming from air filter housing. The lower wasn’t secured properly and was causing stalling when starting. Easy fix for me
