Finally got the engine running as smooth as silk for about a month after putting in 02 sensor, new plugs and points, air filter, oil change and 4 hole injectors. Driving in the North GA mountains last weekend and as I started down a grade, I noticed a drag in the momentum for about a second and then it released for about 5 seconds and then did it again. I "felt" the drag and then noticed a small decrease in RPM's every time it did it. I have checked the MAP sensor vacuum line and that isn't an issue. I searched the website and couldn't find a duplicate of this issue. Now I notice it every time I approach a red light or prepare to turn somewhere. Not sure where to look next. All the Cruiser tips have been completed and I am stumped. Could something be "grabbing" in the transmission? Any help will be appreciated!
