Chevrolet: My 2004 trailblazer acts like it has bad gas. Power

Customer Question

My 2004 trailblazer acts like it has bad gas. Power slows then it takes off real fast. Hesitates speeds up. Yesterday it stalled. Started right back up and stalled again once I stopped again. No trouble starting again. Could this be the ignition or a bad fuel pump?

are you near a Pep Boys or Auto Zone ? if so can you swing by either place and they will read the code or codes set for free in the computer and once we know what code numbers are set we will know the area of your problem
