Here is an another Injector Issue Thread...
Yeah here it is, another injector issue thread. Iíve been doing my reading, my searching and its time for my thread about how much my truck hates me.
The truck is a 2004 F250 6.0 (early 04 engine). Has just under 80k.
Here is a little history of the truck. Bought the truck with 63k and change.
Got home did an oil change and fuel filters (had aftermarket junk on there) and at the time used Motorcraft oil (worked at the dealership all 15qts cost me 25bucks).
Started to drive the truck for a while. Did another oil change to switch over to Amsoil 15w40 and did the coolant filter. Also installed exhaust and SCT tuner. This was all around the 70k mark.
Started noticing coolant loss, so planned my flush and studs, gather the parts for the flush and around February I flushed the coolant system and did ELC. By the end of April got all parts together to studs, and I did EVERYTHING while I was in there. Studs, egr delete, new just about everything and updated everything (that nice discount at ford helped).
Week later dropped a valve in cylinder 3 (found out later the valve had 2 small cracks in it and it was just a bad timing after all I just went threw doing gaskets and all), so we pulled the cab again, new valve, piston, rod and injector. That was all around 75k. Both times I had the engine apart used Amsoil and new filters.
After a couple of weeks I started noticing I was getting contribution codes, 85% of the time is was cylinder 5 and every so often id get a random one. Did some digging and found everyoneís favorite tool, Rev-x. Bought some and put it in, noticed better started and smoother running and contribution codes tapered off, still got 5 from time to time. When I got theses codes it was both hot or cold motor, and after a hard pull or full throttle run or going up a hill loading up the truck. I would start to notice bucking and miss like in the engine, not a completely dead miss. Let off throttle or get to the top of the hill and at idle would really feel it for a little, start going and it would sorta clear up, but if the truck went back to a stop/idle you could feel it for a little (usually around a minute or 2 this would happen). Never got a MIL just stored codes. The condition would clear up and drive like nothing happened until the next time.
Around the same time I started noticing my ficm voltage started it drop a little. Over a couple months Ficm voltage started getting bad, and contribution codes more frequent.
Then it was time for Diesel Nationals at Etown Speedway, well my truck didnít want to go, "miss and bucking" wouldnít clear up and we ended up leaving the truck at home. The next week the truck sat in the driveway awaiting funds to buy a new film and bought a Swaps 58v FICM with a tune. Installed that and things were looking up. A whole hell of a lot better starting and running. The ďconditionĒ happened after first install but didnít come back after putting some miles on the truck.
Week or two pass and it starts its ďconditionĒ again. This time it no longer had a random cylinder it was always just 5. It slowly started getting worse, meaning more frequent. So next step was to do an oil change, I was about 1200 miles early but I was planning on doing the Rotella T-6 5w40 swap over, and rev-x again. Did the oil change and it helped a little bit.
Now on start up it starts a little harder, but only with the tune installed (tried both stock and tuned, but the file is causing that concern) but I also get a little bit of buck and miss at initial start up lasts maybe 2-3 seconds and comes from the odd side bank. Goes away and clears right up. Sometimes how ever it will do that and clear up and about 10 seconds later start its bucking and missing and stay like that, drive the truck away after letting warm for a minute and it will clear right up.
So on the internet I went, found myself late night on ebay (bad news right there), and found someone selling an Alliant Power brand new in box injector, its not the ford reman units itís a brand new one. So what do I do, I place a bid on it. A few days later, get an email ďI wonĒ. Bought a new injector for about 200 shipped and no core, and im just waiting on that to arrive at my door on Monday.
Last night, however I went out after fixing my laptop and getting AE running again went out and plugged it in. its been about a week since I checked codes and it has acted up a bunch of times in that week. Pulled up codes and low and behold cylinder 5 contribution code, but now I have cylinder 3, yup that brand new injector that I just put in less then 5k miles ago is popping a code. I havenít seen that cylinder before get the code.
Now my head hurts, im tired of fighting problems with this truck, ive done nothing but do the best for it, and here I am again about empty my wallet (which doesnít have much in it to begin with) to fix this truck.
Iíve checked everything from wires to connectors to having good filters and oils to the power balance test. I am a technician so I know my way around the engine, and what to look for and where to look. I havenít driven the truck yet to see if cylinder 3 comes back but that will be later today. I guess what im asking is what did I miss, where should I go from here. At this point I am going to replace cylinder 5 and pray to all the car gods that it solves this at least until I have a job again and can afford to either get new injectors all 8 or have the ones I have rebuilt and cleaned.
Sorry for such a long rant and story, but id rather have the whole history there and answer questions and take advice from there.
Thank you in advanced.
