running rich

Too Afraid to Ask

When a car runs 'rich', it has too much fuel in the air mix, which can waste gas and make the engine run poorly.

Technical Definition

Running rich means the engine's air-fuel mixture has more fuel than needed for efficient combustion, often leading to excess fuel consumption and potential engine damage.
