My car is a 97 izuzu trooper, it has started to hesitate when excelerating at 40 miles per hour after driving about 20 or 22miles, Once the engine cooled, it ran ok, then it would hesitate again I was told to have the airflow sensor replaced which I did and add Lucas to the gas tank. This helped some, I can longer before is starts hesitating again. I was told it was not the fuel pump beacuse the car never stalled out. What else could be the problem. Any advise you can give me would be wonderful. Thank You
