Question Problem android 4.x ROMS

hi everyone.
I'm from argentina and I have a problem with notifications using any android 4.x ROM, the only one which has worked for me was SexyNogenMOD based on Android 4.1.2 and kernel QWERTY 2.6.3. notifications work well only using the program Wake My Android Pro, otherwise I couldn't figure out the combination for this to work well.
I'm actually using Vurrut 2.3 KPU ROM, which works great! (using Wake My Droid program), but sometimes I want to install programs that only work on android 4+ and well, I cannot.
My phone is I9003L and using EFS files from my distribution ROM.
Does anyone experimented issues like this? or does any know how can I solve this? using any other android notifications are always late
