Throttle Body Cleaning
Is it easy for me to do this myself at home? I am afraid that I might damage something, or am I worrying too much?
Any input or instructions would be appreciated.

Mine's an '07 with 35,000 miles - the idling has become quite rough and RPMs dip almost to the point that the car feels like it is going to stall when stopped at a red light or reversing.
I might be comparing an apple to an orange, but my Accord had rough idling and eventually threw off a code saying it needed the throttle body cleaned. When the mechanic cleaned it up the idling was smooth to the point that you couldn't tell that the engine is on. Also, the RPMs were higher on idling than before.

Corvette's MAF doesn't like to be messed with. Your problem could be fuel related so I would put a bottle of Lucas or Techron in the car to see if that fixes it. Heck two bottles for the next two tanks might be better. What brand gas do you use?

You are right, you are comparing an apple to an orange. The problem with small 4 bangers is that you will notice a decrease in power or running quality quick.

Sounds more like a dirty MAF sensor. ONLY use the proper cleaner. Even then
, easy to **** up. Do you have an aftermarket oiled fabric air filter?

I have the stock filter. If I take the car to a mechanic is there a chance he could screw my MAF sensor?

For starters, stick with using a Top Tier gasoline.
I had throttle body issues in my other vehicles until I started using Amsoil Performance Improver.
Haven't added to my GS yet, however I will soon.

I would hope that any mechanic would be able to clean it.
FYI, The MAF is the tube just past the filter. It has a small filament wire that the car heats and attempts to maintain at a constant temp. The incoming air constantly cools it and the car calculates exactly how much voltage it takes to keep it at an exact temp.
If it gets dirty or gummed up the dirt will insulate it and throw off the whole process. There is a very specific cleaner made to spray off the filament. Using anything else will likely gum it up and cause the problem you are trying to fix. Someone linked a thread where someone tried to clean it with Sea foam. Bad idea, did not work well. If you get the cleaner and do it yourself, just don't blast it hard. It is a very thin delicate wire.

Not that hard to do if you are the least bit mechanically inclined. Get some MAF cleaner and some throttle body cleaner. You can do both while you have your air intake apart. You spray the throttle body cleaner past the MAF. Usually, but not always, if the MAF if gummed up or not working correctly the computer will throw a check engine code. Good luck. Let us know how it turns out.
