I own a 1998 Lexus ES300. I have 47000 miles on the car and recently when I start my engine, it starts up but then it dies right away. To compensate for this problem, I rev up my engine by pressing down on the accelerator so the rpm is reving at around 3500 for a couple of minutes. At the point, I release my accelerator and the car runs fine. What's this problem? It never stalls once the car gets going though.
