What is the code(s), most likely the code will indicate the idle circuit is at fault. What your car has is what we've called "Rolling idle". Try to clean the throttle plate and see if it help:
One of the most common cause is air in the cooling system. Check the coolant level, top it off and there's a bleeder screw (12 mm in size) at the engine thermostat housing, bleed the air out of it while the engine is at idle.

The FITV (Fast Idle Thermal Valve) is another one common cause, try to clean it:
If not the ICV (Idle Control Valve) need to be replaced. Shop around because the price may be less:

Sounds like IAC, idle air controller, or a sensor. Cheaper to have a mechanic fix it than change every part it could be.
Take it to autozone… They will runa diagnostics test for FREE! I promise!
- Check engine light, open door light, and batterie light all came on and won't go off? 2000 Honda Odyssey I already had the altinator replaced it a month old. The batterie almost a year old. Would the belt need be changed or something else?
- My check engine light was flashing yesterday and now it's off, and today my red oil change light was flashing earlier and then stopped? What does that mean? I drive a Honda Accord, if that helps. My car is driving fine (just a slight jerking every now and then, but that's another issue i'll get fixed). The fact that it did that then stopped worries me… Help?!
- IMA and Check Engine light on in 2005 Honda Accord Hybrid? I was driving for a good 30 minutes and then the IMA and Check Engine warning lights came on. When I got home I shut off my car and turned it back on and the IMA light was gone but the Check Engine light is still on.
- Check engine light on after adding #91 gas to a 05 honda accord? I normally just use #87, under which my car runs pretty good. However to see the difference of premium gas i added about 10 gallons #91 mixing with 5 gallons of #87 which was originally in the tank to my car. After few minutes of driving check engine light was on. Could #91 gas caused it? What should I do?
