i turn the engine on then when i rev it it dies on me. the only thing i can think of is the sensor by the heater hose that is not connected. it has a red and green wire. does red go on top or green? i dont now what else is causing it to die. we changed the tranny we took the engine out now its in the car it dies. i can drive it when i give it gas but when i let go of the gas it turn off. help
