2005 Ford Mustang GT Problems

Spark Plugs May be Difficult to Remove

Our technicians tell us the spark plugs in this engine can be very difficult to remove. Ford has issued a service bulletin (08-7-6) to address this issue, which includes a recommended procedure on how to remove the plugs. Failure to follow the recommended procedure can result in the one or more spark plugs breaking off in the cylinder head.

The recommend procedure is as follows. Using this procedure will greatly reduce the chance of breaking a spark plug.

1. Break the spark plugs loose when the engine is warm.
2. Turn each plug 1/8 to 1/4 turn and soak the treads with 1/2 to 3/4 teaspoon of Motorcraft Carburetor Tune-Up Cleaner or a quality penetrating oil. Do not try to remove the plugs at this time.
3. Let the threads soak for at least 15 minutes.
4. After the soak period, tighten and loosen each spark plug, working it back and forth until the turning effort is reduced. Then, you can remove the spark plug.

There are special tools available to remove the broken spark plugs and repair shops will often charge additional labor time, over and above the quoted spark plug replacement cost, for the removal of each broken spark plug.

Fuel filling issues due to manufacturing defect in fuel tank

when filling up the nozzle will click and will make it hard to fill with fuel. Ford had a service bulletin that called for a replacement of the fuel tank with a revised tank that has a larger inlet at the tank. this will solve the issue as I have done dozens of them.

Buzzing Type Noise From Upper Engine Area

4.0L V6 engines may develop a buzzing type noise from the upper engine area at about 1900 RPM, under light acceleration. Our technicians tell us this can be caused by loose ignition coil bracket bolts. Coil bracket bolts should be checked for the correct torque before further diagnoses is performed.

2005 Ford Mustang GT Reviews

An interesting car. Car still has its original tires and the original battery and wiper blades were changed out in 2013. I bought this auto trans car from the original owner back in 2011 with 6k original miles. It was kept in a garage, covered, still smelled and looked new but it kept killing the battery. I bought it for a song after totaling my 1998 GT but that's another story. Did some r...
Best car I have ever owned. A few minor issues in the first year with TSB's which were fixed by dealer. Only routine maintenance, a couple set of tires, a battery, front brakes, and thousands of gallons of gas in over 100,000 miles of pure driving pleasure.
Nothing but problems with throttle body after the warranty was up. Rocking sound system but burned cd's skip to the point that they can't be played at all. Beautiful car but will not buy another one.
