Hi there, I just purchased a 95 Eagle Talon ESI FWD 2.0 ATran (non turbo)

I have a few question if anyone could help!

I have one question, driving at 90/km I am sitting at 2000 rpm is this normal for the eagle?

And I have one issue, I can be driving steady anywhere between 55-70kmh and the engine revs up and goes back down(doesn't do it below 55 or above 70 or when overdrive is off)....just wondering what this could be?

Thanks a lot, Mike
