Ok I had a b16 in before and it was running.. I just put in an ls and I can't get it to turn on UNLeSS I press the gas all the way down but it will sound like **** and as soon as I let go of the pedal it cuts off.. The cel stays on and I can't retrieve the code cuz who knows where it's at with the wire tuck that was done to it ... Please help.. There's 1 plug not connected and it's the one on the intake manifold at the top right..
