mrsel3, Try clean the Mass Air Flow Sensor. This sensor gets dirty and doesn't allow enough gas in, and the check engine light come on at higher RPM. http://us.lexusownersclub.com/forums/index...t=0entry75467 Good luck.

82DMC12, I got the same problem with 171 code, so I clean the Mass Air Flow Sensor and the problem went away. I'm 90% sure you have the same problem. Here is the picture I took of Mass Air Flow Sensor (look for oldrx300): http://us.lexusownersclub.com/forums/index...t=0entry75467 Good luck and hope this will help save you some money, OldRx300

RX in NC, Thank you for the head up with various sensors problems. So far I was able to clean the IACV and the MAF. No more engine check light for now, but I'm sure I will run into your problem soon (my rx300 is at 73K miles). Please keep us update with what dealer replaced on your rx300.

Found it. Took out the 2 air intake hoses and the IACV locates right under them. I took out the two screws and cleaned the inside with the throttle body cleaner. The problem went away, so here is the pictures I took (IACV is the black piece with the two screws, one of them has the yellow dot on it). Thank you.

Where is the Mass Air Flow Sensor? I looked around the forums but it's not clear where it is or what it's look like.

Hi, Did you able to find a picture of IACV? I'm looking for it myself, just wonder if you already found it. Thank you.

Car Starts, Then Quits. Possibly Fuel Filter?
