Revving at Idle

[Gnestovia]

Does the Mirage have a Idle Air Control Valve?

I don't think anything with drive by wire throttle has a seperate iac. It uses the motor that moves the butterfly as an iac rather than using an old style plunger type that used to gum up.

No sir, I bought it used. At least an old man was the only owner and the only thing wrong was he bumped his fence and dented the driver fender and rear quarter panel for which I popped them out easy! So I was thinking the coils. If not, injectors. But couldn't be cause I ran seafoam through them and cleaned them. Then there is spark plugs. On an another tread here, I put the new NGK in. Lastly, a vaccum leak. Which i don't believe there is one. I wonder if a MAF sensor or throttle body sensor being dirty would cause issues? It's a mystery for sure. I'll get er figured out.

Updates!

Update: At least I reply.

So, I've cleaned the sensors and the throttle body and ran injector cleaner through so far, and still has the issue. For what I can tell and look at, there isn't a vacuum leak. So I'm going to guess the coils. If I purchase a set from Amazon and they don't fix the problem, I can at least return them. So that will be my next try. Wish me luck!

Quick question Gnestovia: did you turn off automatic AC control on your 2015? Can't remember if you've answered this and I didn't find a reference to it in your Garage entry.

Update!

So it ended up being the Ignition Coils. As soon as I install the new ones, the revving problem went away and runs super smooth! And the cool thing is they are blue colored to match my blue accents. So it's all good now!

Hey that's good news right there, and it's good to have good news these days.

Does anyone else recall an ignition coil problem reported?

I replaced one years ago on a 2015. Only it would miss pretty bad if you floored it, check engine light flashed. I changed the single junk coil rather than all 3.

Mine was replaced under warranty from the previous owner, just one.
