I went back and tried it this morning with the same results. I checked all the connection and hoses. nothing is crimped or blocked and all the sensors are plugged in . the only thing i didn't do last night when installing was unhook the battery. I don't know if this is a have to do thing. I have put in a few CAI and have never done it. i tried to put the stock air intake back on and it still just stalls. I am out of ideas hopefully someone has had this happen and can shed some light on it
