7.3 NO POWER
1999 Powerstroke has no power. I was getting a code PO470. I changed the Exaust Back Pressure sensor, and the replaced the tube. Now I am getting code: P0471 Exhaust Back Pressure Sensor Circuit Performance.
It seems that If I disconnect the MAP Sensor, I get excellent performance, but then I get the map sensor code. |
