bad injector(s)

[holokosta]

So my car threw a code the other day and once i hooked up the reader i got an "injector circuit relay" code.

So i'm running Techron through for 4 or 5 tanks and its helping but if it doesn't fully fix my problem I think i am going to do a whole set...

any advice on sized and brands i should think about? I know that I currently have upgraded injectors but im not sure what i have (the joys of buying someone elses toy). SO best next thing, buy all new ones.

Any ideas?
