I have a 2005 Chrysler Sebring. In December the timing belt failed while I was driving down the road. I had the dealership I purchased the car from replace the timing belt as well as the water pump while they were at it. Ever since I have had and issue with it vibrating at idle. At first it was making a whining noise as well. I took it back and they told me that they had installed the belt too tight. Afterwards I still had an idle issue although the vibration was a little different. I also could distinctly hear the belt hitting the casing a few times. I took it back again and they stated that the belt had been put on too loose. So now they have adjusted the belt again and it I am no longer having the whining or belt hitting the casing. But I still have an idle issue. It has changed again and is kind of a pulsing vibration. I can feel it in the brake pedal when I am at stops. I seem to hear the pulsing while driving as well but this may be from my new tires as well.
During this whole readjustment process they have not mentioned actually checking the timing. Just the belt tension itself. When I first reported the idle issue after they put the timing belt and water pump on they told me that it could not be related to timing and that it had to be an ignition issue. But I asked a work associate who used to work as a mechanic and he stated that it would be a timing issue.
I am going to contact the dealership and ask them to check the timing belt again but I would like some advise to see if this the right track.
I never had this idle issue before the new timing belt.
