Stopping Idling Irregularity Please Help!!

Hello Friends, I have a 207 1.6 Vti 2009 model dynamic car with 150 thousand miles on it for 2 years. There is a problem that I can not solve since I bought the car. I am writing with all the details and waiting for your help. The car starts with a misfire when it first starts, then it collects the idle, *After the car warms up, it is close to stopping at a red light, the engine misfires and seems to stall. *Sometimes it cannot collect and stalls. *It gives a rich fuel mixture error. *When I look at my second oxygen sensor from the odb device, it does not read data, only reads voltage. *When I turn on the air conditioner the revs work as it should and my problem is gone, when the air conditioner is off the engine cannot keep the idle steady it goes down to 500 and that makes the car ridiculous, usually when I ease off the gas it is close to stopping or when I give and take off the gas in idle it drops below idle. * I go from Istanbul to Edirne on a long road without throttle the car does not cause any problems but whenever I start stop and go traffic the car becomes cruel to me, when I am about to stop it gives gas to collect its own idle and since it is automatic the car pushes itself forward. When I first bought the car it had LPG, first I had the LPG removed and changed the spark plug cables. The spark plugs, coil, PVC valve, fuel pump, throttle body, MAP sensor, 1st oxygen sensor, crank sensor, brain BSI were replaced, timing chain was replaced, catalyst was cancelled and my problem was not solved. I take the vehicle to Peugeot technicians, they say they cannot look at it, I take it to mini service, BMW service, they say there is no problem with the engine of this vehicle, I could not solve my problem. I kindly ask for your help.

I had a similar problem years ago, but my car was a WV Polo Classic, LPG, 99 model, it was the same, I was starting it in the morning, when I stopped at the lights, the idle was dancing, it was making me pull hard until it warmed up, the car's traction and handling were great, but I was on the verge of selling it, especially in the winter, because of this problem. I did a lot of research in the past, I went to a lot of technicians in Çorlu, most of them didn't even look, they just brushed it off, etc. Anyway, OBD devices like these weren't common at that time, I read an article on a foreign website and I did the same. What could it be? What was done before, we didn't disassemble it like you, there was no room left, the technicians did a lot of things, from the throttle body to the exhaust, but we couldn't get any results. There is a lambda sensor at the manifold outlet. That sensor affects the vehicle's workings a lot, both in gasoline and diesel. I bought original parts and replaced them myself. It was a hassle, but then my problem was solved. The vehicle is not the same vehicle, but there are similar scenarios. I don't know, I wanted to write, did you check that sensor? This is the only thing that comes to mind. I hope your problem is solved.

I went last weekend and had a catalytic converter installed. I will replace that sensor this week. When I look at it from the ODB device, there is voltage on that sensor and it seems like it is not reading data. If it is fixed after changing it, I will write back and see if the situation is correct. Thank you very much for your interest.

I also changed the second O2 sensor and it got a little better but it still gives a rich fuel mixture. Could one of the injectors be leaking? Or could the air intake be low? How can I tell?

I drive a 307 gasoline engine. I had a similar problem... especially in the city, after a while, when I stopped at red lights, the idle would dip and stall just as I was starting off. I had everything checked, from the throttle body to the oxygen sensors. Then, instead of having someone from the industry check it, I took it to a service center (not an authorized one). They said it was the fuel pump. They replaced the fuel pump (including the float) and the problem was solved. (The constant smell of gasoline coming from the fuel cap in the back seat of the car was also solved.)

Do you have a gas tank in your vehicle? Have you had your throttle body cleaned? You can do this.

[QUOTE=serdarcan34]Do you have a gas cylinder in your car? / Have you had the throttle body cleaned? Can you do one of these? [/QUOTE] Sir, I don't have a gas cylinder. I had it when I bought it. I had it done a compression test. I had all the LPG removed from my license and so on. I don't like LPG :) I replaced the throttle body completely with a new one.

When I first bought the car, there was no filter in front of the fuel pump. The original one had one. I wonder if the dirt might have clogged the injectors, but I'm not sure. They are 800 TL each, and I don't want to change them now. I've already spent a lot of money because of the mechanics. :)

Hello everyone, I still haven't been able to resolve the problem with my car. When idling, the STFT short term fuel trim indicator fluctuates between -9 and +29, causing the AFR value to fluctuate at absurd levels, causing the RPM to fluctuate, the engine to knock, and it stalls. When I turn on the air conditioning, it fluctuates between -1 and +4, almost stabilizing, and the AFR value fluctuates between 13 and 16. Could one of the bearings attached to the V-belt be stuck? I'm wondering why the idling in a car improves when the air conditioning is on. I can't figure out why there's a mechanical problem. I think it would continue even with the air conditioning on. Does anyone know if the air conditioning bearing needs to be turned for extra rotation? If so, I'll have the V-belt and bearings completely checked. Thanks in advance.

Which city do you live in? If it is on the Anatolian side of Istanbul, I can direct you to someone who can help. By the way, have you updated your vehicle with the original device? The problem is not solved without a software update on 1.6 VTIs. If the v-belt or bearing was broken, it would have made noise long ago.

I live in Istanbul. If you have a contact, please let me know. I haven't had the software updated yet. I'll take it to the service this week and have it done. The service doesn't seem to care much about it because I only took it with this engine once.

I had a similar situation. Could the timing chain be stretched?

Hello friends. I'm new to the forum. Sorry if I write something wrong. I have an unsolvable problem. My car is a Peugeot 206 1.4 XR gasoline. While waiting at traffic lights, the idle speed drops and rises. Sometimes it stalls, sometimes the car recovers itself, that is, it gives gas and adjusts the revs. The throttle body was cleaned and adapted. It seemed to be fixed, but it's still the same. What do you think is the problem? I'm sick of this car. It's turning me off. I wanted to get your opinions. Thank you. Good evening.

First of all hello I am new to you I have a 207 1.6 vti vehicle I bought it before the new year I have used it without any problems until now but for the past 1 week I have had a stalling problem too. Oxygen sensors have been changed, crank sensor, temperature sensor has been changed in many places but the result is the same. When I stop at the lights the speed goes up and down and sometimes it stalls. The traction and handling of the vehicle is very good. A friend of mine who is a Peugeot master said that it can also be done with Vanos. If something like that happens it will be expensive. Is there anyone else who has this problem besides our friend? Has the problem been solved? NOTE: We connected the vehicle to the device and there is no fault and the light does not turn on. Enes_072023-08-17 10:28:42

Hello, welcome aboard. Buy Motul's injector cleaner, add it to the tank while the gas is at a quarter tank, and use it until the red light comes on. If the problem persists, replace the fuel filter and have the idle sensor and throttle body checked.

Hello Mr. Can, thank you for your answer. I'll be buying injector cleaner as soon as possible. I'll change the fuel filter at my next service. I'm asking because I don't know. My car is a gasoline vehicle. Do I pour the injector cleaner directly into the gas tank?

Hello, you're welcome. Pour the injector cleaner into the gas tank.
