Anyone have injector balance rate specs?
I looked at a 1999 F250 7.3 today. The owner said the truck has always had a "miss in it" every since he got it. He has owned it for 3 years. He says it misses in the "lower rpm range" and it "isn't very noticeable" but he would like to get it fixed because it annoys him. There are no active codes, and no codes stored in the memory. I checked the balance rates. Nothing appeared out of the ordinary except for cylinder 8. It was way higher than the other 7 cylinders. It was consistently running between 4.8 and 5.0. The other 7 were between .1 and 2.1. Anyone know how high they need to be before they are considered bad? I could not hear any fuel knocking at any rpm.
