An attentive car owner always carefully monitors the condition of his vehicle, and tries to eliminate any malfunctions as soon as they arise. If the car has very high revs, then there is probably an overconsumption of gasoline. By getting rid of this, you can significantly save on fuel.
Necessary
- - clamps;
- - new gaskets;
- - set of tools;
- - user manual.
Instructions
Step 1
Before starting work, determine the exact RPM level that is recommended specifically for your vehicle. The instruction manual will help you with this. If the revolutions of the car do not drop after the engine has warmed up, or they simply "float", look for a malfunction. First, try to find out what type of engine was installed by the manufacturer in your car - carburetor or injection. If you have to deal with a carburetor engine, then you can set it up yourself and without much difficulty.
Step 2
Check carefully all hoses and rubber seals. A torn gasket can also cause increased idle as more air than needs to flow into the system. Pay due attention to the gaskets and pipes that lead to the intake manifold. Try to get through the rubber hoses neatly while observing the revs in parallel. If at the moment when you press on any of the hoses, the speed drops, the problem has been identified. Check every connection. Replace worn hose clamps as air can leak if they are loose.
Step 3
If the manufacturer has installed an injection engine in your vehicle, then do not try to reduce the speed level mechanically. The problem is that the revs depend directly on the firmware that was "poured" into the car. In other words, the level is controlled by software. Install an on-board computer, so you will be able to monitor the speed level on-line.
