04 Harley Davidson f250 6.0 powerstroke
smokes white no coolant loss sounds of a miss at idle no power or throttle response if i hold it down for a while rpms eventually come up and miss goes away
has codes cyl 1 thru 8 low has had ficm death code p0611 a while back but is gone now have tryed another ficm since the smoke came no success cyl 6 contribution/inballence so i changed injector #6. the smoke smells of fuel burns the eyes and is still there
what are the possible causes i think the injectors are not closing data stream indicates oil at 950psi when 930psi is required seams low but its only asking for 930 i know these are susposed to be around 1200psi right? exhaust back pressure seems high at 20psi when it used to be 17psi still high
i have removed the cat otherwise stock no tunes no egr delete stock stock stock mileage has been bad 12mpg since i got it a year ago
now i have injector #2 contribution/inballence code up i think its a symptom not the problem any questions or comments are greatly appreciated
i also have had that miss followed by water in fuel light with no throttle response and there is no water to be found in the filter also in the data stream i have 2 oil temp readings one seams normal one is -6500 degrees the scanner im using is a evo looks just like the mac but blue and cheaper have done buzz test failed all 8 low after putting a new injector in 6 another symptom ficm voltage on the right screw is 47 at all rpms and 47 in the data stream

well that`s not it new filters to the list

lets see what can cause overfueling and white smoke
* ficm - checked 47 volts also tryed another
* poor main grounds maybe - checked anyways
* replaced injector #6 scanner told me to p0278
* fuel filers done on recommendation of motorboy

recap codes
p0261 cyl 1 injector circuit low
p0264 cyl 2 injector circuit low
p0267 cyl 3 injector circuit low
p0270 cyl 4 injector circuit low
p0273 cyl 5 injector circuit low
p0276 cyl 6 injector circuit low
p0279 cyl 7 injector circuit low
p0282 cyl 8 injector circuit low
these came up on a injector buzz test
