GregH Posted March 22, 2007 Share Posted March 22, 2007 I've got an '08 F-250 that started bucking and jerking on the customer at 2700 miles. Babied it home, then brought it to us the next morning. P0087 in memory, and cannot get the symptom to replicate. Freeze frame showed 2200 psi fuel pressure at 60% load at highway speed. I would have expected much higher fuel pressure. Oil is overfull by 2 quarts or so and smells of fuel. Pulled the valve covers and ran the high pressure test. No fuel leakage observed, and commanded fuel pressure matched measured by 100 psi or so. Hotline has told me to watch the low pressure fuel system and look for an increase while rerunning the high pressure test. If it increases, then I have an injector failing. If it doesn't, they are recommending a high pressure pump. What do you guys think? Quote Link to comment Share on other sites More sharing options...
