Engine Speed per Cylinder

The "Engine Speed per Cylinder" table clearly shows that the cylinder with the lowest engine speed is the weakest.

As a result, the measured value is well suited as a confirmation in cases of frequent missing which can not be identified with certainty by use of the engine speed graphic example.

Since these values represent an average of individual values, intermittent missing can not be identified.

Intermittent misses can only be identified and evaluated by means of the sample graphic illustration.

Before starting repair work based on test results, the vehicle should be evaluated from the driver's seat and compared to typical production vehicles. (Vehicles with automatic transmissions should be evaluated with the transmission in a drive range.)

In such a case, test results can not replace individual judgment and the experience of a specialist.
