The 89 has no distributor, but does have a module. It will get worse sooner or later. When one of mine acted up, it was about 10 minutes, then 8 minutes, then it left me on the side of the road in a subzero snowstorm. Had it towed 7 miles home. Started it the next morning and it ran for 2 minutes. Put in a new module and its been fine ever since about 2003.
