1986 6.9 problems
 

86 f250 6.9. Not sure how many miles are on it but I've had it for about a year. Ive been having a rough idle. Sometimes it would die on me at stop signs but as long as i was over 1000rpms it ran fine even more power than usual. I have replace all the return lines and o rings and also i don't use my rear tank and ran new lines to bypass that switch on the frame and the old water separator. After i ran the new fuel lines it ran like a top intel the idle problems started. I have new injectors on the way. Any suggestions would be appreciated

Probably need to bump your idle up to 800-850 ... Run about 2 quarts of dextron ATF and run in down good long stretch of highway .... Should help a bit ... If not ... Proceed in replacing injectors ...:tu:

Thanks for the advice. Now i took it to work this morning it ran pretty good but on the way home i could barley make it up a hill. I was only going about 20mph floored no power it was just bogging out. Injection Pump?
