I'm having problems driving. I'm not sure how to explain this so bare with me. When I'm driving and go to shift and let the rpms drop the car wants to die and sometimes does. Then if driving and just put the car in nuetral the will car die. So today I checked over everything on the car made sure I didnt have any vaccum leaks zip tied everything. I put on a hks bov today. Cause the last bov had a little hole on the back so it would let out alittle air and I thought that maybe the problem. But it still dies and I don't know why.
