Honda Accord Idle Issue

[Micsm08]

I know this isn’t a Honda Civic, but I have a 2002 Honda Accord that drops rpms when it starts. When cranking the car it seems fine until a few seconds passes, then rpms drop super low and the motor begins to shake. I’ve noticed that when I crank it and give it some gas that it will stay running until I let off. Then it begins to drop and shake again.

Check this thread about cleaning the IACV & stuff.

In that thread, it describes how to set your BASE idle (which is not the same as the operating idle). Then reset your ECU and let it re-learn the behavior of the idle system.

Also check the idle screws.

Recently, my obd2 scanner gives me the code "P0108: Manifold Absolute snaptube vidmate Pressure / Barometric Pressure Sensor Circuit High".

OK?
So have you tried testing the MAP sensor?
