All good advice - I'm not about to undertake the task of disassembling the UIM - I'm not that confident in my abilities. I'm comfortable removing the MAF to get directly at the TB, but I'm just don't see myself taking off the UIM.
Good advice about spraying the TB cleaner into the TB - what my problem is, though, is that I remember someone saying in an earlier thread that you need to spray the TB cleaner directly into the inside of the TB - which requires opening the butterfly valve - or else you aren't being thorough.
Can I just leave the car at idle, pull the nozzle of the TB cleaner back a few more inches, and just spray it directly at the closed butterfly valve? Will that achieve the results that I am looking for; i.e., getting a thorough cleaning?
For the record, I'm not blasting/flooding the TB with the cleaner. I give it a 2 or 3 second shot, wait about 10 seconds, give it another 2 or 3 second shot, wait 10 seconds, so on and so forth.
Thanks.
