This problem is hard to describe, but when just cruising down the road at speed the car will sometimes hesitate for an instant and then pick up again. Since the CEL never comes on I find it hard to believe it's a misfire, and wonder whether it might be the tranny searching for a lower gear for an instant. The car is an automatic. Once it did hesitate for an instant when starting out from a light.
My neighbor has the same car, and when I told her the story she said hers does the same thing. Meanwhile both cars continue to run with no other symptoms or warning lights coming on. I don't know about her, but I tend to cruise at about 75mph to 80.
Any ideas as to what's going on here?
Thanks
Sheldon
