My wife has been complaining the RX for couple of months. She said the RX struggle from 30mph to 50mph. I am planning to replace spark plug and air filter. What else did I miss?
History: 1). I have 150k miles on the clock,
2). major service from dealer at 90k mile. I forgot spark plug were changed or not at that time.
3). Tranny fluid change at 120k mile
4). Oil change every 7k mile
5). No code found when checking with ODB II
Thanks guys!

Call the dealer to check if the plugs were changed or look at the invoice.
Clear out the history by removing battery for 20 min or so.
Play with the shift point change [non-economy if your RX has one .. '99 RX has a switch]
Finally, what are you comparing with?

I mean when I try to change lance or pass somebody. I gas but the car accelerates from 30 to 50 mph slower than before. It has been going on for a few weeks. I have never disconnected the battery…should I do that?

Same reason, I'd disconnect it before I went to the track back in Mexico to 'clear' out my commuting driving habits during the week.

Alternatively, if you don't want to lose radio station/clock/seat presets, you could pull out the EFI fuse for about 10 seconds (minute preferable), https://www.clublexus.com/forums/2786328-post15.html and then put it back in, without disconnecting the battery.
Also a free way to try to clear check engine lights.

3). clean iacv (Thanks tcheung87)
4). Add fuel injection cleaner with premium gas
5). check tranny fluid level and it is accurated
The result: better and I need more tested driving to said it back to normal. Thanks guys!
