How's the air filter?

Your a tech, so I can assume no codes?

When you cleaned the tb, did you check the free movement of the butterfly?

When you have the problem, is the motor hot, or cold?

Well, there are some updates, but I don't think any addressed that problem.

But, they might include the updates when running the tests.
They normally charge 1 hr labour to do the reflash, but if your paying for the test, you might get it included.
