The reason for the sharp change in turnover can be a few simple or more complex: Air filter: before or after flow-meter.Malfunction or pollution control idle. Defective valve EGR.Cracks in the exhaust manifold due to overheating (as a result of a dirty air filter. The failure of the spark plugs is the result of the bad fuel. The control unit firmware failed.
- Air filter.
- A pump air pump (before or after the flowmeter).
- Idle or pollution control idle.
- Defective EGR valve.
- A fractures to the exhaust manifold in the exhaust manifold.
- The throttle of the throttle (as a consequence of a car with a dirty air filter.
- Ignition of spark plugs as a result of contact with bad fuel.
- The control unit firmware failed.
The reason for the speed of the revolutions in the VAZ-2110 may also be the wear of the sensor position of the throttle.
