My name is Roy Dobson, and I have a 1997 Buick LeSabre Limited.
I have had this car for about 7 months now, and in June of this year, I was going on vacation, when all of the sudden the RPM gauge started to chug at low RPM speed (about 1000-2500 RPM).
Now when I sped up, it would be fine and would not do it for a minute, then it would do it again. It was a little noticeable when you would drive on a level grade, but when you started to go uphill, it would get worse.
It only seems to do it when the car is warm, and I took it to Canadian Tire for a diagnostic, and they said nothing was wrong, even on the road test.
If anyone has any ideas, could you please email me with a solution of what it could be at email@example.com
That would be very appreciated.
