My Enclave started missing with my cruise on about 9 months ago while returning from a long trip. When I would take the cruise off it would stop. Then it began doing it without the cruise on. Seemed to do more so when going up a slight upward slant on the highway. Took it in to the dealership and was told a spark plug needed to be replaced. It worked fine for about 4 months. Then started to do it again. Took it in again and the spark plug was replaced again. Drove fine for 4 days. Then right back to missing again. They say they can not find anything else wrong with it. Any ideas?
