Throughout this site we use many technical terms, and given the breadth of readership our site enjoys, sometimes we are remiss and incorrectly assume everyone knows what we are referring to. For those that do not, here are some explanations of the technical terms use. |

Refers to an engine’s performance being poor in one particular part of the rev range. Can be described as a hesitation, or interruption in torque produced by the engine, due to ignition irregularity (such as high cylinder pressure causing excessive resistance at the plug gap) or carburettor failure such as temporarily weak mixture during acceleration. |
