Replacing one injector?
Just bought a good truck a while back it has a slight blue white haze once in a while took it to 2 different shops had balance rates checked and a po. 304 code came up number 4 miss fire and balance rates came back good except this one was higher. You can feel it miss fire once in a while when sitting at intersections then it clears up and seems to be good. I was wondering since its so close to xmas I was thinking of changing just the one for now. Would this fix my smoke issue for the time being both shops wanted 3500-4000 to change all four on that side seems a bit high? Thanks

With the amount of work required to replace injectors on an lb7 I would do all 4 while your in there. I wouldn't want to tear it down again a few miles later to do the other 3.

For that price most shops do all 8. I have seen people do 1 at a time, but afterone is replaced another goes within a few weeks to months. Its alot of work so it would be cheaper to do at least 1 side if not both.

So a full injector job would be 7 to 8k! Fire up those 7 cylinders & drive south....just keep driving south.
Seriously though you and a buddy could print a DIY & knock it out for 800 plus the return line seals. Spend that money on your family, it's Christmas!

Were it mine, and the injectors have been done about 80,000 miles ago, I would do just one. So long as I can be sure which injector it is, it is only going to cost $200 for the injector and a few bucks for gaskets and seals. Most of these gaskets are reusable and so you don't need to replace them anyhow. If you do buy the $200 gasket kit, you wouldn't have to buy it again for the next one. From everything i have read, you chances are about the same of a reman injector going bad as they are of a good injector doing the same. I'll take the gamble, but I do all my own work. If I was paying for labor I would have the whole bank done, it at least gets you some sort of warranty.
