Faults and Fixes
Why does the engine hunt or stall at idle?
Idle hunting is usually on the fuel side: an air leak at a connection, a filter beginning to block or injector imbalance. On electronic engines the fault record often gives the cause directly.
Why it works this way
A cylinder balance test taken with a diagnostic tool shows which cylinder is falling behind as a number rather than as an impression.
