2000 Rx300, Unstable Idle Problem
MY GIRLFRIEND WAS STOPPED AT A STOP LIGHT AND OUR 2000 RX 300 STALLED OUT. WHEN THE TEMPERATURE OUTSIDE GOES UP, THE CAR'S IDLE GETS VERY UNSTABLE. THIS IS THE FIRST TIME IT HAS ACTUALLY "DIED" ON HER, BUT STARTED RIGHT UP AGAIN. DOES ANYONE KNOW WHAT THIS IS CAUSED FROM?

Sorry for the late reply. I believ ethis due to a device called Idle Control Valve. I just acquired a 99 RX300 and I looked the service history. The last owner already replace that twice. Not a very good sign to me.
mine never did that and mine never had any occasions of it doing that!! contact ur lexus dealer about this..

Help RX300 running rich . Idol dropping at complete stops
Many help would be great
1999 RX300. V6 automatic transmission

Low idol

My educated guess saids it's going to be the fuel pressure regulator

You will need adapters to fit pressure gauge and then specs to measure the line pressure and volume (flow) to narrow down the fuel delivery issue.
Dont forget o include quality of fuel.
Fuel injectors.
Air intake (oxygen sensor).
