Question about 1999 Honda Passport

1999 Honda Passport idle problem-no check engine light on

My 4WD passport idles anywhere from 2400 to 3300 RPM. I changed a couple of sensors for a check engine light about 4 months ago and the light went out. The light has not come on even though this idle is way out of normal zones. I added some injector cleaner to a tank of gas but that hasn't worked. Any ideas?

    My check engine light is off, but the engine is idling about 3000 RPM. I've already changed the IAC, with no change. When I disconnect the battery, it resets for a couple of days, then starts idling higher again. What could be causing this?

TRY SPRAYING BRAKE CLEAN AROUND THE INTAKE ALONG THE VALVE COVERS IF THE IDLE CHANGES YOU HAVE BAD INTAKE GASKETS ALSO LOOK AT THE FUEL PRESSURE REGULTOR PULL THE HOSE OFF IF THERE IS GAS IN THE HOSE THEN YOU HAVE A BAD REGULATOR

Change air filter and clean throttle body this should increase your rpm preventing the car from shutting down

1999 Honda passport won't idle at less than 1000rpm. Gas gauge inoperable


I doubt the two problems are connected.
The high idle could be a vac leak or a sticky idle speed control valve.

I have a 1999 Honda passport 3.2 liter engine that is idling high. I replaced the tps which helped somewhat. When I stand outside the car and start it, it idles fine. But when I sit in the drivers


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.

yes the tps could be the problem, but you need to use a scanner to determine the problem, don't just randomly replace parts, you could also have a problem with the air flow sensor, again use a scanner to determine the problem
