Hello Jetta car algebra is not cold, what is it a little cold at 3000 rpm

Hello, in this case, it is recommended to first check whether the refrigerant is missing, and then check the refrigeration pipeline to see if there is any blockage.

The idle time of the Jetta car is not cold, and the cooling point of the high speed should be caused by the lack of refrigerant R134A in the air conditioner, and the refrigerant can be installed in time.

Hello, it may be caused by too much carbon deposit, clean the throttle and fuel injector, and check the thermostat failure.

It should be the lack of fluorine or abnormal pressure inside the air-conditioning system, which causes the air-conditioning compressor to work intermittently; Or the engine has a low idle speed or a drop in power.

Hello, you can first check the working condition of the compressor, whether the refrigerant is missing, and then check the air conditioning system.

Hello, check the working condition of the compressor and whether the refrigerant is missing. Take a comprehensive look at the air conditioning system.

You seem to have this situation mainly caused by a damaged aircon compressor, it is recommended that you go to the repair shop to check the aircon pressure.

Hello, this should be caused by a lack of freon, you can repair the shop or 4S to test the pressure of the pipeline, if necessary.

Hello, this should be caused by insufficient pipeline pressure, you can add a refrigerant and try again.

In this case, check whether the condensation is missing, the compressor is working, whether the pipeline is blocked, and whether the pressure is normal.

In such a situation, it is necessary to check the air conditioner compressor. Go to the repair shop and check the pressure of his air conditioner.

The high and low blood pressure teachers were normal.

Hello. Is it that the gasoline filter is dirty or that there is a problem with the oil pump?

Hello, that's because the pressure of your oil stick is not enough, see if the gasoline filter is dirty, if it is dirty, you can change it, if it is not dirty, the oil stick is broken.

It's likely to be a problem with the oil pump relay, so try another one! Anyway, it's useless, you can keep it for later!

It should be that the car's gasoline is fogging problematic, which means that the air is not getting in enough or the gasoline concentration is too high. I guess I'll have to go to the garage for a minor maintenance. Clean throttle valves or fuel injectors, etc.

It's too cold, and the oil supply solenoid valve and the oil circuit are caused by carbon deposits.

When the cool car starts, more than 1000 points are normal, and the normal is about 900.

It's a bit high, about 850 revolutions normally.

Except for the fo type. The others are all 800 rpm and idle in place.

Hello dear! Engine idle adjustment method: When the engine idle operation is unstable, it should be adjusted when the engine temperature is normal, and the oil and circuit are not faulty.

Use a screwdriver (commonly known as a screwdriver, change cone) to slowly release the throttle opening adjustment screw, and when the engine is about to be turned off, screw in a little to keep the engine running. Adjust the idle mixture adjustment screw. Bring the engine to rpm.

Idling 3800 rpm??? I want to destroy the engine!

Generally, the idle speed is about 800 rpm. The engine speed of 3800 rpm is not low.

Check the spark plug, cylinder wire, ignition coil, my car a few days ago can not get on 5000 rpm, bought the ignition coil, cylinder wire, spark plug, after the change, it is better to remove the cylinder line, no, and then install it, remove the ignition coil, install the old one, no problem, it means that it is a problem with the cylinder line, return the ignition coil, the spark plug can not be returned, when buying something, say good, ask people to acquiesce to return, a little to buy good things, loading parts, cylinder line ** is about 180---200, Ignition coil 260---300, spark plug 80 yuan.
