Lexus Repair: LexusRX300, fuel pressure regulator, vacuum leaks

Question
I have a 2000 rx300.  The engine dies right after it starts, once it warms up it runs fine.  Any ideas?

Answer
I would look at vacuum leaks on the intake system. Also the EVAP & Fuel pressure regulator hoses also.
Clean the throttle plate, and if equipped, the idle valve & EGR valves. (I don't remember off hand if you v6 has the dual electronic throttlebodies & vvt-i, or the single throttlebody with the said valves.)


If there are any stored ECU codes - the engine light is ON -  I would get them scanned for free at someplace like a parts store (Like an Autozone) to see what your own computer says.
