no, you remove the the MAF from the car when cleaning it, it is super easy to remove, takes like 60 seconds with air tools
by the way, MAF cleaner is much nicer to work with than throttle body or intake cleaner - it is not the cancer in can that those others are!
but it is not strong enough for cleaning your intake butterfly etc.

these are the types of posts that are more inclined to produce helpful information

and its these procedures that will help anyone towards finding a problem..just sayin

just sayin
- I think the dozens of success stories in the ECU caps thread and other threads on here speak for themselves - anyone who hasn't yet realized that ECU capacitors are one of the most common issues on older LS400 and SC models not running or shifting right, has apparently been living under a rock! 
Other than the ECU capacitors, unless someone has done something silly, like cleaning an AFM with solvent, or getting the plug wires on out of order, or pinching an important wire like the cam sensor or issues stemming from wire damage from slamming etc. - LS 400 just doesn't tend to have running or shifting issues, making ECU capacitors the number one suspect, as this is, at this point, quite a well-known factory defect!

I have changed all of my caps in my ECU...though it did not solve the problem in its entirety, it solved many other minor issues to which I didnt and wouldnt even think could have been the ECU....

look im not taking anything away from u and ur work here cowboy..u r an asset here no doubt, but...u tell people about the caps on every single post u make and make it seem that its an end all resolve. u also tell people who have little experience or knowledge to replce their caps and when it doesn't solve the issue u say..well maybe it wasn't done correctly or used the wrong caps..i believe it would be much more helpful if u guided them in the right direction on how to determine if the ecm is in fact the culprit...that's my only issue,other than that, u have gone beyond what most do around here...its like my boss who is smart, but his issue is he thinks he knows everything and when I prove him wrong he will go to extremes to prove he is right..he knows a lot but doesn't know everything

guys keep to topic.
While the ECU is a somewhat common issue, it is not, and should not, be the first thing to be replaced/fixed. I've seen a fairly large number of threads and far more often than not people throw multiple parts at the car then try to pin success on any single one of them.
While repairing the ECU may be good practice for some on a 1st/early 2nd gen, it should by no means be the first step diagnosis in place of going through relevent components (ie- ignition/fuel systems, etc... depending on the issue).

It amazes me how people will understand something like "hey your strut bar bushings are bad, they all go bad", or "your transmission mounts are bad, they always go bad prematurely", but when it comes to ECU caps, even otherwise intelligent people are in denial!

Incidentally, does your Celsior have the correct ECU or does it have all correct sensors?
I have seen some Celsiors which were installed unusual ECU or sensors by mechanics who were desperate to fix the car. Other than those, I also have seen damaged connectors or wires caused by the rough handling. Some mechanics even replace the ECU without disconnecting the battery cable and it often partially damages the ECU. Some of them are not familiar to electronics and they amaze me often.
I say, "Don't do that." But they say, "What's wrong?"
For some of them, what they can't see by their eyes are beyond their understandings. Electrons can be only seen using measuring equipments, you know.
Modern cars use variety of technologies and are designed by engineers from different fields. But it is hard for those who do the repair job understanding everything. They sometimes mess the car up. I had some bad experience with them and I mostly fix cars around me myself. I even fix cars at shops as a volunteer time to time. Shop owners invite me for a good dinner as well as they allow me to use tools and equipments though.
I don't know the history of your Celsior but what I worry about is that yours is one of those which was given up to repair by mechanics in Japan.
