2008 Buick Enclave hesitates when accelerating

What to do about an engine hesitation on acceleration?

Is the check engine light on? How many miles on your Enclave? Have you taken it in for service of this problem?

bad mass air flow sensor is one possibility

But there are many possibilities

We need much more information, please

I’m going to assume the check engine light is on . . .

What codes do you have?
