i have a manual non turbo 97 eclipse and when im driving on the highway in 5th gear and im going 70 mph my rpm is at 3000. is that normal? becuase i also have a 96 toyota camry that is a automatic, and when im going 70 mph in that the rpm is at 2500. are all cars different or is there something wrong wit my eclipse? because it seems to run fine with no problems.
