After driving for a while and letting the car set,it will stumble when started. It almost dies,but doesn't.Doesn't happen all the time.It will do that for a few minutes and then will run fine,and it may or may not do it on the next start.I replaced the TPS sensor since it was under warranty,but it didn't help.There aren't any codes in the computer either. The car still runs strong after that initial hiccup.I have been smelling a slight hint of gas,but not sure if they are related.Any ideas?

 

What all has been done to the car? Might be something simple like needs a tune up or replacing the fuel filter. Have you done any maintence on the car latley? There are several things that need to be kept up on on these cars, so it help to know how well the car is kept up.
