Stalling at a stop

La semaine dernière, j'ai remarqué que lorsque je suis arrêté dans la circulation et mon jauge de temps est d'au moins 210 ma voiture tombe au ralenti et remonte, mais parfois il tombe et se coupe et je dois redémarrer. J'ai lu à propos de la soupape d'aspiration de carburant, mais je peux avoir un demi-réservoir, quart réservoir ou plein réservoir, il n'a pas d'importance si ma température est autour 210, il le fera sinon il ne fait pas. Tout le monde sait ce que ça pourrait être. Ma voiture est un 09 avec 53000 miles. Tout conseil est apprécié

Vanne de régulation ?

I was thinking that but I seen people say they were throwing codes and I'm not throwing any

This is happening to me as well. I have zero codes thrown. My idle is fine but sometimes when i'm coasting or coming to a stop, the car will die.

Are you going to take it to a dealership?

Mine does this since it had about 2,000 miles on it. Dealer replaced some idle actuator, something, two or three times. It's been good 20k+ miles since and I still have it on occasion. It, however, only stalled once, but it gets almost to that point quite often. No codes. It is not temperature related though.

Just don't stop, easy fix...or, take that puppy in. Too much speculation, could be a lot of things.

Only in stopped traffic?

My Idle bounces around while stopped at lights, traffic etc.. Never dies out but it drops down to around 500 rpm goes back up to normal idle, I'm hoping its not an issue that gets progressively worse and eventually starts stalling like OP claims.

It will. Classic idle air control valve symptom. Trust me, you'll want this fixed sooner than later. When you can't keep an idle without your foot on the pedal, you pretty much can't drive the car.

For me yes and when Temps are around 210. I will definitely look to replace this valve asap. Thought I seen something saYing it's 80 dollars from ecs and I'll be doing it mysel

Exact same symptoms on my car. How difficult is the diy to replace this valve? If it's just $80 I might do it myself if not too complex..

I have the same issue as well. If anyone has already replaced the valves please post a DIY if you have the time.

Thank you!

This?

Thanks Decimation! Will definitely look into this.

Get your fuel purge valve replaced. Fixed it for me.

Did the idle control valve change and it was a waste of money

Rod bearings.

Thank you as well Yay-Z.

It looks like it may be the fuel tank breather valve for me as I've seen the symptoms both after a fuel up and when the tank is nearly empty. Also, I have not seen any idling irregularities while the car is moving which leads me to believe that it isn't the idle control valve.

I did a little searching and found another helpful DIY in case anyone is having the same issues as me:

Glad to see my diy is helping people out.

Ordered the fuel tank breather valve will be tackling this next weekend I'll let you know if it fixes it
