Throttle Body Cleaning
On all of my cars with EFI in the past I have periodically removed the throttle body and gave it a good cleaning along with the MAF and checked all the vacuum hoses and replaced the PCV valve also. Any one out there been doing this procedure on their Acura?
Really haven't had to do any thing but change oil and spark plugs once since owning this ride, lot different than the BMW 5 series before the Acura. The old car I had to be on top of it all the time. I did have the timing belt installed along with water pump and tensioner but that was at 100k miles. At 100k miles had me thinking the TB should be removed and cleaned. They do have a tendency to accumulate carbon after a while.

For what it's worth, I recently had to remove the entire air intake, and I was genuinely surprised with how clean the MAF sensor was, as well as how clean the TB was. I didn't look inside the intake manifold though. The car has almost 95k miles on it.
Intake systems continuously get better on cars - as long as you are using the proper filter and do not have any damage or loose connections, I would venture to say that you are fine. On my '85 Trans Am, I do recall cleaning the TB once. But that was a GM car that is older than I am.
You can check your MAF with just one fastener I believe, pulling it out of the intake hose. Just be careful - the sensors are pretty sensitive (and expensive).
I figure if you're not experiencing performance loss/MPG loss, or getting codes, you're probably fine.

Mine cars get a thorough once-over before winter and the TB gets a cleaning if it needs it.
But I'm a little OCD, so there's that...

I'm pushing 70 and have been around. Worked and managed a automotive machine shop , where we had everything except a crank lathe. Had very strong autos in my day, including a 66 Ford Galaxie R Code (look that one up)
Always worked on my own stuff except when needing a lift to make things happen. Have been a salesman on the road for the last 30 years traveling the east coast , commission only. My RDX has 101,000 miles on her now
no problems what so ever , which is good because now I pay to have things done that I wouldn;t bat an eye lid over a few years back. In my older cars Volvos , Bmw's and such , I would clean the TB every 40 k miles. I'll try this
on my own when the weather warms up and get back to the forum with my findings.
