Car Information:
Ford Taurus
Year: 2003
Engine Size: 3.0L
Trans: Automatic

Issue / Question:
After driving in stop and go traffic continuously for 45 minutes or so, my 2003 Taurus will intermittingly start bucking. If I turn the car off for a short period and attempt to start, it will act as if it is not receiving gas or something. It will either start and not want to accelerate or not start at all. After waiting for several hours, I can start the car as if nothing happened. I thought maybe the car overheated but when it occurred today, the temperature of the car was no different than usual. I had to wait about 30 minutes before it would restart. The problem began several weeks after the last oil change when I was convinced (certified mechanic) to use 5w-30w high mileage oil due to the high temp in Florida and the amount of miles of the vehicle (69000). This has occurred 3 times and only after driving for extended periods of time, turn car off for a short period of time and start or try to again.

Answer:
We see these where the liner in the fuel tank fails and this coating gets into the fuel pump and causes this problem. It may require another fuel tank and pump. We can run a fuel pressure test and usually tell what’s up and if the tank needs to be removed. We can look into the tank and see if the liner is failing as well! Trust me on this one we have a 2003 Taurus as a loaner vehicle and just went through the same thing with it and several customer Taurus’s as well. I think it may be the ethanol in our fuel causing this.
