P0172 code on 2000 Honda CR-V. My Honda will idle very low and almost immediately shut off when I hit the brakes such as when I come to a stop light. I am able to start it right back up and it will idle fine when it is turned on in my drive way. I have tried to replace the spark plugs already. My fluids seem fine and air filter is good.

P0172 Fuel trim too rich.

The powertrain system that the vehicle has is a speed density, so a vacuum leak will cause the system to go rich. or the MAP sensor itself. Check the fuel pressure regulator. remove the vacuum hose a see if there is any fuel coming out from there.
