TC indicator

On a very intermittent basis, my TC 'off' indicator comes on and I can feel the "twitch" of the change. Then a few moment to almost a minute later it goes out and I don't see it for some time. This happens in wet and dry conditions. I bought the car with 18" stock wheels on it but soon changed to the 20" Verde that are on it now.

I've had mechanics tell me it's because of the change in wheels/tires. But I know that the outside diameter of the 20" are the same as the 18" set.

Anyone have ideas??

I had my TC light come on before, the first time it went away, the second time my CAI was loose and it messed with my MAF.
