choking

When excelorting the car seems to choke every once in while. Not sure if it is the injectors. I put fuel injector & carburator cleaner into the fuel to see if it will help. Anyother thing I can do to fix the problem before taking it to the shop.

have them cleaned at jiffylube they have a good fuelinjection cleaning also try your air filter if it is really dirty it will cause that,,but definetly the injectors

Thanks for your help....I will have it done this weekend.
