They are not cheap. If you get alliant reman yourself you are looking at about $250 per injector. That's 2K for the parts alone. Shops are proud of their labor and another 1500 wouldn't surprise me. Why are you looking to replace all of them?

Some may recommend replacing them all, but I personally wouldn't unless you know you killed them all with water or something.

Realistically, replacing them yourself is not that hard, it's just time consuming. Hardest part is getting the passenger side valve cover and high pressure oil rail off. I had to use the 40 torx (might be 45) bit and a 1/4 inch wrench to turn it in order to remove the two hardest to get to rail bolts. (don't drop the bit down into the head......) You have to remove quite a few parts to get the valve covers off.

Also, once you get it back together, it will take forever for it to fire off if you do not fill the oil rails with oil before you close it all up.

Again, nothing that takes any real expertise, but it does take some time. Any mediocre mechanic could do it.

I'd also add that if you do this your self to make sure you clean the valve covers and the area around it as best you can. cause you can get dirt stuck in those places and when you brake loose the valve cover you can brake loose the dirt and then it could drop down to some where in the head and that could and probably will find it's way into the hpop system.

I determine this by monitoring the power balance on cold start up

some code readers and tuners will give you a code for cylinder contribution. If you don't have one, you should get a scanner like autoenginuity for a laptop and you can turn cylinders on and off to determine which one is misfiring. It's like $350, but well worth it and it will save you money in the future when avoiding the repair shop.

Also, you might have weak injectors that still have quite a few miles left on them, but your FICM voltage is low and it doesn't have enough voltage to operate the degraded injector.

You may want to pay particular attention to exactly what FICM code your getting a FICM puts out a lot of codes some more critical than others you may have a code representing an issue that needs immediate attention or one you can address later. It really helps to know which ones you may have, its to your benefit cause FICM's ain't cheap.
