Goodbye acceleration lag!
Man, I love this place. Read a thread a few days ago about the delayed acceleration kind of thing and someone mentioned the throttle body. So I was thinking I needed a new one and was pricing them 
Then I found another thread about cleaning the TB and that could help. Holy crap, did it ever! I watched a couple of Youtube vids of guys doing it and figured I could handle it easily and it gave me more time to commune with my "Lil' Blue Darlin'" so I ran up to O'Reillys for some CRC TB Cleaner and started disconnecting stuff. Then I had to go back to buy a deep well 8MM socket I thought I had and didn't (you just need a 10MM and an 8MM for the job.)
Here it is before cleaning. Hint, this was the clean side!
I forgot to snap a pic of the other side, but it was nasty. Big rings of black sludge where the flaps close and a thick layer of yellow on both sides. Sprayed it down a bunch and it broke off a lot and just dripped off, but most of it took some scrubbing and repeated sprays. I didn't get it perfect, but I made an enormous difference and once I re-assembled everything, it felt like a newly-tuned vehicle. I mean really impressive sounding and smooth.
Plus, and here's the best part - THE LAG IS GONE.
Seriously, the accelerator is as smooth as my wife's Sorento and it only cost a few bucks and an hour of effort. I will probably open it up again and take a stiffer brush to it later, but I am pretty impressed with myself ... and TMS right now!

How many miles do you have on your car? I'm at 42k. Do you think it'd be worth cleaning? I know a lot probably has to do with type of driving, environment, etc. Just wondering if it'd be worth digging into or if its really not an issue till higher mileage.

I have read that every 25K or so is good. It sure can't hurt (as long as you remove the TB first!) and it definitely gives you a more intimate relationship with your car.

Here's a question for you on this. Did you have to completely disconnect and remove the throttle body? I am assuming you don't want any of that garbage getting down into the engine.

I remove the TB when I clean it. Only takes about 15 minutes or so to take it off, clean it and put it back on. Makes all the difference in the world in throttle response.

I was having a rough idle and a slight hesitation on light throttle, cleaned out the front of it and around the valves and it cleared that problem up! All the black crap that I got out was nasty.. Going to remove it this spring and clean it totally out! Question though, would I need to get a new gasket or can I re-use the one that's on there?
