The spark plugs are usually flooded in winter because at low temperatures the start-up process of the drive unit is extended and the onboard computer supplies more fuel to the combustion chamber. In the case of spark plugs that are already old, the risk of flooding is much higher than in the case of new candles. Why? Because they give a weak spark, making the ignition last much longer.
What to do when the candles of our vehicle are flooded?
The easiest way is to unscrew the spark plugs and clean them thoroughly. In most cases, those who decide to do so after removing the first spark plug come to the conclusion that they are in a deplorable condition and require immediate replacement. If after unscrewing the candle does not bear significant traces of use, it should be thoroughly dried with a cloth and then screwed.
Remember that this process should be repeated with each candle, not only with half! After drying each candle, it is worth checking if they give the right spark. We can apply the candle to the valve cap of our vehicle and then start the test. If a visible spark appears on the candlelight, we can say that everything works properly.
After checking all the candles, we can start the firing test. We can also try to turn the starter and keep the gas pedal fully forced – there is a chance that after about 10-15 seconds the engine will start.
