1999 Honda Passport LX 6 Cyl 3.2L

Engine

Why is my engine suddenly idling very high after putting in a new battery?

It normally idles around 750-800 in drive & 950-1000 in park or neutral. Now it's just under 1500 in drive, 2000-2500 in park or neutral!

See if idle comes down after starting and idling 5 minutes. As engine coolant warms ECU senses it and adjusts the idle down. Let us know.

The ECU probably needs to recalibrate itself.
