Default 2008 V6 MUSTANG - NOTICED PROBLEM WHEN IDLING

I have a 2008 V6 Mustang, has about 96,000 miles on it. I've noticed a few things have been happening lately with my car. First the harmonic balancer went to ****, along with the belt. My car has been running fine, except I noticed yesterday when I was on my way home from work, about 7 mins from house when I started to slow down to 10mph or lower coming up to the stop light and when idling at the light, my car started to shake a bit (felt it was coming from the engine), not so much jerk and if so it was a very light jerking. Any idea? Thanks

A common idle issue withe these S197's; 4.0L and 4.6L alike; is due to a dirty Throttle Body (TB). It's very easy to clean. Be sure to buy a proper TB cleaner (explain to the guy at the auto parts store) and use a lint-free rag. Unbolt the TB, clean and reuse the old gasket.

Additionally, if the fuel filter hasn't been replaced in the last 30k to 40k miles, now's a good time also. There are a few other things to do/check but those 2 are often the higher percentage items related to idle problems, especially when rolling to a stop.

Hello MUSTANG20084444,

Welcome to the Forum! My name is Deysha with Ford Service, and I recommend you have your vehicle diagnosed at your Ford dealer. Your Service Manager is in the best position to look into this for you. He can check into any assistance, Recalls, or Customer Satisfaction Programs that may apply to your vehicle. Let me know the outcome.
