I was having trouble with my 2004 Chevy Impala hesitating upon takeoff. Thinking that it was needing a tune-up, my husband replaced the spark plugs and wires. But to no avail, that was not the problem. Upon the recommendation through one of my friends, Becky, she told me about Warren's Automotive on Waveland Cutoff Road. We took the car this morning to them. We had them do a diagnostic check. Their finding was two of the main coils were burned. They were able to replace them and get my car back to me within hours. They were very friendly courteous and prompt. The price was very affordable and fair. I would recommend these people to anyone.
