This problem was pretty straight forward using the Navistar Engine Software that led us directly to the problem. The engine code was the fuel rail pressure sensor. Most times it’s the sensor but due diligence is in order here just in case there’s a bad wire end or poor connection down the line. This engine… Continue reading MaxxForce 7 Running Check Engine Code
The video proves how lame the factory electric air horn sounds. I was shocked when I first heard it. It would be the perfect device for an Austin Mini perhaps but not a 40 foot school bus.
