So I have a 2002 RX300 AWD, and when I start it, it will start, rev real low, and then cut off. If I catch it when it revs low, and give it gas, it'll be fine. But it's still got me worried. Does anyone know what's wrong with it?? I love this car to death, and I'll be devastated if I have to get rid of it. =[ Please helpp!!
