Surge, in meteorology, an atmospheric process that operates on oceans and inland waters whereby a change in atmospheric pressure or a high-velocity wind works in conjunction with normal gravitational tides to produce dramatic changes in oceanic circulation, and, oftentimes, flooding in coastal areas.

When to set DTC for engine surge maintenance?
• After driving at 6.25 mph or more, the actual engine idling speed varies from the target idling speed by between 100 and 200 rpm, five times or more during a drive cycle. • If the actual idling speed varies from the target idling speed by more than 200 rpm five times or more during a drive cycle, the ECM illuminates the MIL and sets the DTC.
