All,
I tried to clean the MAF on my 1995 ES 300. Opened up the round piece with MAF mounted on it but didn't really find any screws to get to the two wires mentioned here and in the pictures. Inside the round piece I see all plastic stuff.
Can anybody refer me to an ES300 specific picture please.
Many thanks in advance.

Sounds like you were just cleaning the air temp. sensor that is built into the MAF sensor. The part of the MAF sensor that needs cleaning are the two small wires inside the tubeHere is a cleaning procedure:
You can't clean the MAF using 99% Alcohol like the link suggests - it doesn't work. Use CRC throttle body cleaner in a spray can. Two or three blasts inside will clean the MAF.
Es300 1995 Sluggish - Worse When Hot Outside

Hi All,
I have been reading the lexus service manual in addition to this forum to troubleshoot sluggishness problem with my ES300 1995.
I have cleaned Mass Air Flow sensor. It didn't help much.
Before I do more I wanted to ask if the following observation narrows down the things I should check.
Car is noticeably more sluggish when it is a hot day.
In addition, there is noticeable hum from the engine when I accelerate.
There is no hesitation while running.
There are no starting problems.
Does this point to a specific sensor?
Many thanks for your time.
