I have been reading a lot of posts, about hesitation, and things that can cause it. I think my car is experiencing hesitation. When I hit he gas, it seems to not have a lot of power, and also seems to hardly move. I don't know if I am just imagining this or not, but the ride seems a little rough. Especially in third and fourth gears I notice it. What does it sound like?

You may need to get the injcetors cleaned but first check for error codes. Check your air filter.

Well, I don't have any lights on, so can the codes stll tell me anything? I may try to get the injectors clean
