I have been running a vvti 1j with the Tomei arms setup on 20 lbs for over 5 years now without any real problems. Big thing that helped was going to a power fc djetro and getting rid of the maf

Thanks for the info! my coil packs do look a little beat to be honest, so that's what I was wondering about too. Dumb question, but what is the diverter valve? I turned it up to 12 yesterday and didn't run into anything cutting out, so that's a plus I suppose. Cant figure out this idle issue though.
