2004 6.0 rough idle below 1800 rpm
Hello, I am recently new to site although visited several times over last few years and always found very helpful. Only access right now is through phone, so if I have spelling errors I apologize, dang spell check. I have recently been experiencing very rough idle below 1800, took truck in to shop, came back with error codes for ficm and miss on#5, quoted $2000 for replacement of ficm and #5 injector, but recommended I do all 4 on the side so now were over $3000 for that. I have been doing a lot of online research, and found you can get your ficm repaired by ficmfixer.com for as little as $110, and no need for programming. Has anyone used this service and how long did it take, I live in Wisconsin. Also I have been reading a lot about the updated program removing horsepower and tanking fuel economy, also that Ford was doing this without telling customer. When I heard this I was thinking wtf cause about 2 years ago I took my truck in to dealer for balljoints and never really thought about it much till now that is around the time I noticed a big change in my gas mileage and performance drop, a few months later egr valve issues, a few months later plugged oil cooler, cracked egr cooler and blown head gasket. Repairs came to about $7000. Also extended warranty denied coverage saying failure due to sludge build up, a whole different issue though as far as the warrant company goes. To stay on track here now I am a year later with more problems. Are us guys thinking Ford secretly reprogrammed our trucks crazy or is it a legitimate issue? Also would like any info on the reprogramming of the ficm. Also I am thinking of buying the ae scanner, would this tell me what program is on my ficm? Dealership could not tell me, said I would need to come in for a $160 diagnostic scan. Also anyone tried hotshots secret for 6.0 liter injector problems, site says 86% success rate with faulty injectors, looking for any feed back before I drive truck another 500-1000 miles, after adding oil treatment. Even with all the problems I am very pleased with the truck, has never left me stranded, and even now when you hammer on the gas there is a couple second hesitation but she takes off. I have been driving the truck very limited lately and lookin for feedback if I should be driving it at all. Any info at all would be greatly appreciated, like I said found very helpful info here before.
