I will try to take it to them and have it tested although all of a sudden the car starts great lately. Whatever.

Here is an example of something wrong with my car:

At the 0:10 mark you can here a change in the engine tone and power.

And under, I'd say a 10% throttle, cruising, the car would work its way down to 1400-1500 rpms and studder. So I think if I change out the module that I was talking about earlier, I think it will fix the problem.
