I changed my upper intake a week ago and I thought put everything back where I thought it should go but after a two days of driving the car stalls and with a jump I take it home. I took out the battery and alternator to get them checked and both are fine. All connection are clean. But there is one electrical connector/plug i couldn't find a home for and it's right around the alternator. Its part of the cluster of wires that goes on top of the engine and connect to each fuel injector and whatever else. i'm not sure if thats the issue but theres a power drain some where
