I did the spark plug change over the weekend. Took me 6 hours to do, not really a hard job , just takes a period of time to reach the back plugs.

Unfortunately on the reassemble I must have mis-matched the air lines somewhere, because on start up, my "maintenance soon" light flashes 3 times then goes off. Idle is butter smooth and the RX 330 drives smooth. I do notice a dip in mpg though, I can't get over 20 mpg after the spark plug change.

Does anybody have a vacuum diagram for this vehicle? There is a 3 prong connector that has lines coming off the air tube going to it. I only have 2 lines connecting to the 3 prong connector and I can't seem to find the 3rd air line anywhere.

I have the AWD RX 330.

Ok thanks!

Maintenance soon is for your oil service friend.

As for the lines, even if the two off the air box were mismatched, it's still pulling a vacuum from the same area. Just FYI.

I have 3250 miles left before I have to change my oil, using synthetic. Yesterday I found out what my problem was. The second air tube below the main tube was not hooked up to the white jar , also the air box. Which was causing a major vacuum leak. Once I hooked the tubes back up and took the RX out for a spin. The mpg came back after a 15 mile drive. Problem solved.

The maintenance required light will come on and stay on every 5000 miles until you reset it. Here is how you do that:

Make sure the odometer is set to total miles not trip. With the key in the off position, push in and hold the odometer button (ODO). Turn the key to the on position without starting the car. Continue to hold in the odometer reset button until the maintenance required light goes off (about 20 seconds).

Thanks! Very similar procedure resetting the oil light in the GS. Mine just flashes 3 times then goes off in my RX. I will try this when I get home.
