For about a week now this idles rough when you come to a stop or a parked. Replaced spark plugs, put in injector cleaner and still rough idles. Took it to the garage 2 days ago and they could't find anything. All they said was spark is good and yes it does idle rough. Gee really! So I guess I am going to need to take this in AGAIN. Any ideas on what I could tell them to check this time? Also there are no engine codes. My guess is that if it is something electrical, it may be on its way out and the computer hasn't sensed it yet. I just bought this from a dealer and just made my first payment on the 1st. Also I should mention, while driving it runs just fine. No loss of power at all.
I posted this a week ago also and have had very little response so please help.
Thank you very much for your time.

I have run into the same problem, what I found was bad plug wires. Also check your fuel filter. Did you put fuel injector cleaner in the tank, or had the fuel injectors flushed? You say you just got it from a dealer? I don't know the laws in your state for used vehicles, but here where I am from, if you purchase your vehicle from a dealer there is a mandatory three month warranty. You may want to look into that.

Fuel injection cleaner has been put in three times. Plug wires are fine. I am in Canada and there are no 3 month warranty laws here. I am calling the dealer back today and I will see what they say.
