    Ok, we have code P0505, the IAC is ok, but we have an intake leak which is what Harley said is probably throwing the code.

    We have a 2007 Heritage FLSTC. Hubby just did a 96 to 103 upgrade and evidentially the intake gasket did not seal properly.

    He is taking it off this weekend and re-sealing, is there a trick to to make sure the gaskets seal?

    Thanks,

    Prior to ripping things apart, suggest that he make another pass on all the fasteners to make sure that everything is tight. Sometimes a last round with the torque wrench or 1/4" drive ratchet can find something that was over-looked. If not, make sure he uses new gaskets, orings, seals, etc. where ever he had things apart. Even if he used new ones when he upgraded, better to go get some more new ones since they may have been damaged on the last install.

    I think that he should spray around the intake with some brake or carb cleaner and find out in fact that he does have an intake leak. No sense taking it apart if that is not the problem.

    Yeah he did the spray test and there is a leak. We have all new gaskets, etc. to put on just wondering if there is a way/trick to make sure it seals properly. We put all new on when we did the upgrade but evidentially it didn't seal properly.

    As indicated above, before tearing things apart, make sure the current setup is snug like it is supposed to be.

    If it must be torn into, make sure the mating surfaces are clean with no residue from the previous sealing material left on either side of the joined area. Unless the book calls for it, I would avoid using silicone or other "sealants". Also make sure that the joining surfaces are carefully aligned and not set at an angle.

    TQ

    Also make sure you are putting the seals in the right direction.
