I have something similar now. Not only when warming up, but almost constantly throttles. Sometimes about 1500, and sometimes about 2000. But sometimes up to 3000. It started yesterday. I’m still monitoring...
Yes, air leaks are an option. Pay attention when you stand on the brake to see if the vacuum seal hisses. And how the revs behave. Check everything under the hood. Are the rubber plugs in place?
If everything is ok, start with cheap sensors.
Thanks for the advice, I'll try it
I don’t recommend flushing the IAC, my third IAC just runs out after washing it with carburetor. Just change it. Recently I started to increase the speed, changed it - everything is fine now.
TPDZ. Rare disgusting. I don’t remember which one. Change it and don’t be surprised if the show starts again in a month.
DU. As a spare part, it seems to me to last forever. I rarely hear that the damper itself breaks down, unless the spring weakens.
Lastly. DMRV. Repeatedly caused spontaneous increases in speed. But it's expensive. Therefore, it is better to check it diagnostically.
For the last two days, the idle speed has been floating, sometimes it shudders violently, as if it wanted to stall, but at the last moment I changed my mind) I was lighting the car here alone, and when I started it, the voltage dropped a lot, somewhere down to 10V. Could this be somehow connected? ECU bosch 17.9.7
SOLUTION: There was air leakage through the receiver rings.
Priora sometimes floats

First, flash the ECU with the stock verified firmware, wash the injectors, eliminate the CPA

I haven’t gotten around to chip tuning yet, although I had that idea. This means I didn’t check or wash the injectors in vain. I didn’t turn off the KPA, I just checked the leaks. I'll check.
John
Where does this info come from?
Jector
John
in this case, the desired speed remains the same, and regulation comes at the expense of the UOZ?
is this motor 21126? Have you looked at the timing belt?
brownie Kuzma
Yes, this motor. I didn't look at the belt or phases. I'll take a look. It starts up normally, so I didn’t look in that direction, apparently in vain. I'm somewhat leaning towards CPA, MMAGS
, suggested eliminating it, should I plug both tubes? Or maybe it’s still DS? After all, after disconnecting the DS, the glitch disappeared. There was a bad contact, for example. True, no matter how hard I looked, I didn’t catch the speed appearing on the scanner while swimming. Software, I think, has nothing to do with it. This defect mainly occurs after turning it off and restarting it again. For the first time, even the drop in speed immediately after starting was like when the DP was clogged. Then, each time, less and less often, and after cleaning the contacts, the DS no longer appeared. I'll call the client today to clarify. It seems like a minor malfunction, but the feeling of dissatisfaction remains. Moreover, the client did not like the other diagnostician we have in the village. And he asked me for several business cards. Trust must be justified.

Now I called the client, the defect has not appeared again.

Today I observed something similar on 21114 from M73, walking around the scanner coincides with the regulation of the DC, enriched - they grew, poorer - fell
I still don’t understand why
(rule gauges)

, pay attention to the reference and phases
I suspect the scanner's OZ is not true

I checked and noticed no deviations. And at the moment of the glitch I didn’t look. Guilty. The client promised to come right away. No swimming yet.
Why? For what reason does this happen? I looked at STM-5 and S-7000. The readings are one to one, only the STM has more digits after the decimal point, and the S-7000 rounds. And it’s the same thing. (this also applies to other parameters).
I will check its work using the methods from the site.
John
No, it doesn’t interfere, it has its own with the BC in the tidy, the SMS-diag connection is good.

And I have the same problem with gas
sorry I sent it to the wrong place
you remove the terminal, you remove the throttle, you take out the sensors, you take the gasoline, you wash it, then you blow it with a compressor, you wipe it dry with a cloth, you collect everything in a heap, but you don’t start it right away, but you turn on the ignition and turn it off, and so on 10 times, then you start it up and everything should work. I’ve done this more than once and everything is fine.
Idle speed regulator
The throttle is electronic, all processes there are regulated by a valve, there is nothing on it except a gearbox
I need to wash the throttle body and everything will go away. I’ve had this happen twice
I'm afraid to clean it, they say that after illiterate actions it can break
You can’t open it with your fingers and that’s it
How do you open it, press the pedals or something?
The mass air flow sensor has nothing to do with it; it’s on the Bosch 17.9.7 frequency type. and on the net there is not a single case of someone dying. without a computer it's a finger in the sky to look
First, clean the DPKV throttle position sensor and look at it. what is the mileage of the car? did he tighten the masses?
Somewhere around 184,000, I hit the masses, I don’t remember when. There is no such sensor
Yes, you take the throttle valve apart and there is something inside.
)) I definitely won’t take it apart. If it doesn't come with maintenance from the factory, then that's how it should be.
Your mileage is decent and the tracks could have already erased the glitches from here.
How to say. This is the mileage of the engine. Everything that is attached has about 65,000 miles on it

Is Dpkv serviced?
Of course you need to clean it. all sorts of garbage sticks to it
There's some kind of magnet there, I think it doesn't care about dirt

I apologize for intruding))) but this is also the problem. When warmed up, the revs begin to float. and with them the speedometer needle. Mostly in traffic jams. replaced the speed sensor. I replaced the air flow sensor and replaced the throttle valve with no results. I don’t know where to dig anymore
stretch the masses onto the car
The engine chokes when you press the gas pedal
Yes, I'm stuck, full throttle at idle. but everyone understood))) There are such moronic sellers, then you buy yourself a gift like this and you will suffer, although you will not even think about what they did with this car. forester.sg5 xt 03′ legacy b4.bl5 gt 08′ hr-v gh4 00′ forester.sh5 xt 08′
At idle speed (i.e. in neutral), pressing the gas pedal to the floor is impossible? IMHO, you're being picky
