i went and picked my motor up from hondamotorsonline.com. steve is a great guy and does guarantee all the sensors work. he let me pick from 4 jdm h22's with lsd when i went to get it. i drove all the way from AZ just so i could hand pick it. it runs strong, as you can see from my sig

it's just having a sputtering problem, which is most likely just dirty injectors im hoping. give him a call and see what he can do for you.
