If of those were hooked up wrong you should get a code. I also would bet its air i just put injectors in my 03 it sat for a year and a half without running it took a long time cranking it before it would start.
My 03 idles rough and it does not go away with rpms my injectors are all within 2.xx mm3 and it has a new cp3 any idea? Also no smoke at all and it still runs good.
