This engine is known for vacuum leaks, so before you start throwing oxygen sensors at the problem, it pays to perform some diagnostics. Start by cleaning the MAF sensor. Spray the sensor with CRC MAF sensor cleaner (even though Ford tells you to replace it because it can’t be cleaned). Next, check the plastic vacuum lines, especially where they meet with rubber boots. If they are cracked or the rubber … Read More
