Well i was driving my 82 280zx non turbo today to school and about 10miles into the commute my car started to loose power. I was going about 70-75mph when all of a sudden it felt like the transmission disengaged or something. I would give it gas and nothing. I changed to lower gears and nothing i kept trying it until it finally kiked in.
The only change i have made to the car recently is that i put in a new battery last night. I also was running late and i didn't have time to warm it up. But it didnt give me a problem until 10miles in, by then it was warmed up.
Any ideas what might be going on?
