My 97 7.3L engine seems to go to pretty high rpm prior to shifting and once I reach 55 mph will go up and down about 2,000 rpm. It’s almost like having a Jake brake set itself for about three seconds and then off for a few seconds, Jake again for three, off again for few.
My brother thinks this could be the low pressure oil pump not pushing the injectors sufficiently? I’ve got 280,000 miles on her, I’d like to keep her on the road for a while longer.
Please help! Thank you.
