    So I got a navigator recently and when at a stop in hear a strange horn kinda pressure noise and the truck almost wants to stahl out but if I hit the gas it goes away for a little bit but comes. Back at the next stop and only does it when ideal has any one else experienced this issue yo

    First thing that come to my mind is a vacuum leak. If the noise is happening only when the brake is applied, replace the brake booster check valve ($5). Otherwise, check the vacuum lines around the engine while it's running for leaks, collapsed lines, etc.

    You know what I figured it out its the butterfly valve on the throttle body I believe so it could be ideal control valve going bad
    I'm going to take a look at it this weekend and check what it should be ☠
