apowers2k:
After some extensive reasearch the last couple of days I have found that the MOST common cause is the fuel pump in the tank is going bad. Also the fuel pump monitor. Also did some looking into the factory service manuals and although there is a fuel temp sensor listed in the emmissions manual, it IS NOT used on any of the Mustangs. 70% of the time when a fuel temp sensor is mentioned it is in reference to Natural Gas vehicles. The Mustang does have a fuel pressure sensor in the fuel rail and in the fuel tank.
The dealer should be able to a fuel pressure and more importantly a
fuel volume test. They should also do a leakdown test to see if the pump or injectors are the cause of the leakdown. In other words the system does not hold or build the pressure as it should. I would also have them replace the fuel filter at the time the fuel pump is replaced.
Also checked with several Ford dealers in the area and not one of them can remember having to replace a fuel pressure sensor in the fuel rail. They all said that the most common problem is the fuel pump itself.
I was wrong in saying there was no such thing as a fuel temp sensor and got carried away in my zest in saying so. Should have done more reasearch first. But it was proven that the Mustang does not use one, at least thru 2003.
As far as the trans concern/kicking back, I would surmise that the torque converter may be bad also. This is something that you will have to have a Ford Trans Tech verify for you. If possible go for a ride with the service manager or trans tech him/herself. In a few of the Ford dealsers I checked into they may or may not have someone who is VERY knowlegable in Auto transmissions. Some ford dealers will overhaul the trans in order to repair it, other dealers do not have that capability and will just order in a new one if they are convinced that your trans does have a problem. You may want to check at a couple of Ford dealers if possible to find one that will give you the best service.
I hope that this helps you out. Will ask around today about the trans/drivetrain concern some more. If I get anymore feedbck I will let you know.
