Hi all,
I'm having a power loss problem with my 86 E350 6.9 & don't know what to do next. I just brought down both tanks, cleaned out all the guck, replaced fuel lines, new fuel filter. It will idle fine & has power until it's running hot. Then, when I start to go up a grade, it will loose power, at 65 I will drop to 55 going uphill & will recover once I get to level grade. Eventually all the faster I can go is 35.
Injector Return lines have been replaced. Out of my right rear view mirror, I only see some black smoke. The IP was rebuilt a little over a year ago by the previous owner & in that time I only put 3,000 miles on the Van. Total miles are at 128,000.
Thanks
