1g is running a little rough, come to find out injector 4 is not working at idle. above ~1500 rpms it runs smooth and normal. I have evo injectors and they have been fine since I have had them. So now the question, what would cause the injector to not work only on idle. I am going to throw the stock 450's back in tomorrow to see if there is a change. Open to suggestions on other issues or things to check :banghead:
 
that doesn't mean injector isn't working. Just means you have a misfire. Injector could be clogged or leaking. See if it's actually firing or not.
