MAF Sensor Cleaning
Hi Guys,
I read a post on the UK owners site about a RX400H slightly misfiring and the petrol engine kicking in earlier than before - and VERY noticeable when it does so. The solution was to clean the MAF Sensor.
I am experiencing a similar thing with my 2008 RX400H so ordered a highly recommended MAF cleaner, trouble is I cannot get the connector to come off in order to remove the sensor!! I don't want to have to use excessive force in case I loosen some of the wiring in the connector so Has anyone any ideas on a solution?
Many thanks.

Spay some electronics cleaner onto the connector, to loosen gummed dirt. Take flat head screw drive, press down on the clip tab, pull/wiggle plug out. Fortunately, it's in your face easy access. Even if you get like real stuck, no matter what, breaking that locking tab off won't do much damage later, as plug still stays in place real well without it, when re inserted and you can run some tape over it to secure in place. Desperate times call for desperate measures. I don't remember, how long that plug pigtail is, but can't you take sensor out with it still connected? And spray clean right there? Cover engine with some old towel or t shirt.. MAF cleaner evaporates very quickly anyway. Make sure you get cleaner stream all the way up into the sensor bulb, as it's well hidden. Little bulb looking thing.

toyota/lexus doesn't recommend using any type of cleaner. in fact its assembled in a clean room. The one thing i used to clean them is good old compressed air. it should be enough to blow off any dust or debris
