Hello all,

To start, this problem is happening repeatedly to my wife, but I haven't experienced it yet. She drives 45min at 70mph to work and when she gets off the freeway the car stalls/hesitates. It hasn't died onher, but she feels like it is close to dying.

A while back I had a catalytic converter code popping on and off, but it hasn't popped up in a while.

Driving the car, it seems to be a bit more dogged than she used to be, but not all that noticeable driving around down. It sounds like it is fine on the highway, just after pulling off are the problems bad.

Any ideas? I did just clean my K&N at filter (only aftermarket part) and it didnt seem to help. I told her spark plugs would be an OK thing at this point. It's been about 40k miles.
