    Hi folks,

    Before I dive in trying to fix something that isn't broken, any advice on how to treat these CELs on a 1999 550 Maranello?

    P0507 - high idle (although seems to operate around 1100 most of the time)
    P0133 - O2 sensor front bank 1
    P0139 - O2 sensor rear drivers side

    Car has been in storage for about 9 months, just transported from a cold climate in Minnesota to Florida. Took it for a gentle run to warm everything through, everything was great and then the CE light came on just as I was getting home.

    Is bank 1 the same as drivers side (LHD)? Am I right to think it's best to swap out the O2 sensors on drivers side which probably caused the high idle code? Or lean mix / air leak possibility? I also checked pending codes and have P0600, P0562. Have cleared all for now.

    Thanks for any tips in advance.

    Colin.

    Check for vacuum leaks. Intake gaskets are common.

    Colin, which area of Fla are you in? Naples has F1 if you have issues.

    Thanks for the suggestions. I'll try the connectors and any leaks first, if still problems then the O2 sensors. If its beyond me, then I am in SW Florida and familiar with F1 who did a PPI for me on another car, good people. If all is lost, then last resort I could try the "freeze it overnight" option in Minnesota...:)

    I'll post the fix once done as it may help others.
