The MAF sensor tells the engine how much air is going in. If the intake let more air in, the MAF sees it and the injection adjusts the mixture. The mixture will also be altered based on the temperature of the engine (coolant sensor) and the temperature of the air going in. If the air temp sensor is giving inaccurate information, the ECU will alter the fuel mixture inaccurately.Godzildo said:
And, after installing an intake that gives you more air, wouldn't you be more likely to run lean?
