Intermittent power loss at speed
00 supercab 7.3 auto
377000 miles Starts great, runs great, but occasionally it will get power loss at 40-60mph, coupled with shaking and vibration. Cant put my finger on it when and how it comes about. Stepping on pedal just drones and it clears up after a mile or so and all is back to normal. I have Diablo to read codes and sensors. No tune loaded. Only mods are hutch, zoodad and filter. I rebuilt fuel bowl a year ago. I use B99 and #2 diesel.Symptoms are same regardless of fuel type. No water in fuel, and fuel filter new in last 60 days. ---AutoMerged DoublePost--- Went to check fuel filter, and both o-rings on it were stretched about 1 inch too big, could not reinstall them. I guess its the biodiesel 99% that did that. Wonder what other rubber fuel sustem parts might get affected? Gonna go get new fuel filter, and change oil and oil filter as well. Will report back ---AutoMerged DoublePost--- New filter, new oil, full tank of #2 diesel....and it runs like new. Must have been issue with B99 |
