Please help. I have an 08 TL with about 12000 miles and I am having trouble. Apparently the dealer has no idea. Here's the issue my car seems to hesitate to start and make a stuttering noise and slightly shakes.
The dealer replaced my battery(twice!) and also replaced the starter. If anyone has had a similar problem it would be helpful to get some feedback. It does not always happen and seems to occur once the car has started once and sits for about an hour.

Please help!!!!

 

I have the same thing going on.... I nerver really worried about it... I just replaced the batterie to an optima yellow top and the same thing is going on so it cant be that. I dont know might not be something to worry about

 

This exact same thing is going on with my car. Does anyone know a possible fix for this?
