Two different systems, but in parts co-joined.

Probably 2 different problems. The fuel smell may be a small leak from the fuel line connector or fuel injector that is leaking. The high pitch squeal is probably a bearing noise.

noise is complex.
my wild guess, is ? you failed to tighten accessory brackets, etc.

Hi,
You're kidding right?

Is the door open or closed when the idle issue occurs?

This is the same as an Isuzu Rodeo. I'd go look on the Honda/Isuzu online forums for an answer.

Vacuum hose got disconneted,look along the PCV make sure its hooked up,or the brake booster hose either way a vacumm hose is disconnected

There is not a dipstick for the automatic transmission on the 1999 Honda Passport. There are two plugs on the bottom of the transmission - the lowest one is the drain plug and the one located higher is the overfill plug. You should have a fluid temperature gauge as it is recommended that the temperature be between 90* F and 135* F when checking fluid level. (I believe you can order from dealer - I have also heard that running the engine for 10-15 min will put you near the proper temperature - to be certain, the temperature gauge is the right way to do it.) Run engine for a few minutes to reach optimum temperature. The vehicle must be on level ground and at idle to properly check fluid level. With proper temperature reached - and engine running at idle - set parking brake - remove the fill plug and add fluid with a syringe or small pump until it just starts to run out of the opening. Do not open the overfill screw with the engine stopped. Replace the fill plug and shift through gears - then remove and repeat one time to achieve proper level.

Actuator motor on t case if it's electric shift

it is the fuel pump this is normal

POSSIBLE ALTERNATOR INTERFERES WITH RADIO

This is telling you a electrical fault in the 4X4 engagement has occurred, most likely the engagement electric motor, pull it out and test the motor.
