[street 335i]

2013 bmw 335i coupe. AT. Hey everybody, I have been struggling with two injectors. I've replaced them twice now and same thing each time. I check to see if they leak, I install, code and test drive. First test drive works great pulls hard no stumbles or misfire 1-4 WOT. Next day I start it and cylinder 2 and 4 injector codes appear. This has happened twice. Any one have suggestions on what else may be bad? I have been replacing them with used injectors but I check for leaks before install. Let me know

Injectors shut off codes? That does not mean the injector is bad. Usually means a persistent misfire on that cylinder which could be many things...

I replaced the injectors and coded them and they work now. I just had some cheap remanufactured ones that caused the codes. No problems now
