Hello and thanks for using JustAnswer.I will try my best to help you with your question.
I need to know what engine your 2003 Taurus has.
The 4 valve V6 or the 2 valve V6. The 2 valve has the spark plugs next to the exhaust manifold and the 4 valve has the spark plugs in the valve covers.

Customer reply replied 3 years ago
The spark plugs are in the valve cover
Ford Mechanic: A. Penland, Ford Senior Master Technician, ASE replied 3 years ago
Ok, that is the 4 valve V6.
Most of the time, idle concerns are caused by vacuum leaks from the intake manifold gaskets and the PCV hose under the intake manifold in the lower section. You will need to replace the upper and lower intake manifold o rings and the PCV hose. Then disconnect the battery to reset the PCM (Engine Computer).

What Customers are Saying:

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

MollyUSA

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey

I would (and have) recommend your site to others I was quite satisfied with the quality of the information received, the professional with whom I interacted, and the quick response time. Thanks, and be sure that I'll be back whenever I need a question answered in a hurry.
