I have never had anything serious happen with my engine, but I think I am about to have my first episode. I have a early 85 NA. I was driving on the highway last night. Suddenly, my car did a fast jerk, like the engine cut out. It did it a couple other times in about 15 minute intervals. The RMP did not jerk when it happened. I changed oil and spark plugs last week. They also tried to do my rear diff fluid but that did not happen. It seems to only do it around 2500-3000 RMP. Please Help!
