how to adjust the engine speed?
and whether the normal fuel consumption?

 

Your Camry's fuel consumption is quite bad. It converts to 15.6 miles per gallon. It should be in the high 20's, like 28. So it's low by 80%.

The engine idle speed is not adjustable. It is controlled by the ECU, which adjusts the IACV (Idle Air Control Valve) to vary the amount of air entering the engine. It's quite common for this IACV to get dirty and sticky. Try cleaning it per the instructions in these two threads:

Thread 1
Thread 2

 

Thanks for the response to engine speed, but about the fuel consumption is not really understood that about that

 

Has any other maintenance been done or perhaps missed ( not yet performed ) ?

Sparkplugs

EGR

Air filter

 

candles replaced
fuel pump replaced, mesh in the tank, and near the engine,
injectors cleaned and replaced them on the gum,
I have no EGR
replaced the air filter

 

PCV valve maybe. Also the car doesn't smell bad when running does it? like rotten eggs? also check the spark on your ignition coils.

 

I changed the valve to the next, with the exhaust pipe had never smelled rotten eggs, changed the coil and the timer is all new repair kits, candles changed 4 months ago

 

sorry i mean ignition coil

 

I removed one week a catalyst

 

What is your tire pressure?

Do you drive on asphalt road all the time or dirt stone roads?

Also what octane of gasoline are you using? When I travelled in the some parts of east asia , 80 octane was the highest petrol (gasoline) grade available.

 

tire pressure 2.2 bar, tire size 195/65/15,
always food on the paved road, the car is charged with 92 gasoline
the price of gasoline 96 - 1.1$ 92 - 0.75$. 80 - 0.64$ .
I even ran the car with petrol 96 but she uses it, too, that on 92 gasoline, the day I pass an average of 18.64 miles

 

hmmm wait he doesn't have emissions equipment on his car it seems. I was going to say o2 sensors but i don't think you'll have them on your car. when you remove the oil cap is there any smoke?

 

Yes, his location makes offering suggestions difficult. I have no idea how different the control system is on the Camrys Toyota sold in Kazahstan.

 

I'm willing to bet they just have catalytic converters, the US actually has some of the most strict emissions standards in the world.

 

wait! saw an o2 sensor in your picture. have that electrical piece on your exhaust checked out, see if you have a downstream 02 sensor as well and check that. and I would probably check out the catalytic converter if you have one and its possible to look at the media inside.

 

I do see the O2 sensor on the manifold, and the water temp sensors.

The next culprit is the thermostat or the water temperature sensor that is actually making the engine cold , or telling the engine computer that it is cold and to use more gasoline.

 

I changed the thermostat to the new and changed water pump, oxygen sensor, I also changed about a year ago, also changed the temperature sensor for the computer, and I do not have a catalyst, I knocked him because he was all dirty after a poor filling of gasoline, I'll be photo give

 

From your pictures, it looks like the O2 sensor was poisoned by a gasoline additive - the same additive could have also caused problems with the injectors and the EGR valve. The stuff looks like same sort of crud I was dealing with back in the 70's - with the critical difference that the cars back then didn't get poisoned by it. If you haven't already, run injector cleaner through the fuel injectors- the kind you plug into the fuel rail and comes in a pressurized can. The 'in-the-tank' cleaners aren't aggressive enough to cut through the kind of deposits you seem to have. If that doesn't help, you'll likely need to remove and test (or have tested) the injectors for spray pattern and action, i.e. that they properly atomize the fuel and that they respond to the electrical signals.

Orange candle full

once poured me a bad fuel at a gas station, then I washed the entire fuel system, and I have on this orange shit clogged catalyst, a catalyst and I completely removed after

 

dude, change your sparks

 

He already did four months ago. He's calling them candles... No one here has asked the million dollar question. Are you sure the ignition timing is set correctly? What about the timing belt? It could be stretched and causing your cam timing to be off.

 

I changed the timing belt in a year in the ignition exposed as it should be 10 degrees, I even checked himself in the firing angle of diagnosis

 

Have you asked other 2.2L Camry owners in your country, what fuel consumption they are getting?

Timing belt and ignition timing possibly.

Brakes dragging? Transmission problems?

 

consumption of gasoline in other runs from 9 liters to 12 liters or more and I'm going 13,5-16 liters per 100 km
