i have a 95 powerstroke had a bad injector on number 6 so i replaced it ran great for about 20 min i shut it off and went back to start it so i could leave and it ran good for about 30 seconds and ran like complete crap and the check engine light came so i tore it apart and if i unplug an injector on the driver side it will run decent but still has a miss if i plug it back in number six is completely dead and the other three on the drivers arent working properly but if i unplug one of the injectors the other three work fine and i cant figure it any ideas?

 

I would say new set of injectors....

 

I want some more info... How many miles, how did you decide the injector was bad? Who swapped thr new injector in? Did you lube the injector, new orings? What code is being thrown? Theres a few questions to answer.
