Hi , I have a 2005 Is 300, I was just curious, as long as I had it. Iv noticed that it runs at a higher RPM than I would think....at 65-70 mph its almost at 3000 rpm..is this normal for a 5 speed car, my other car is an acura tl it runs at alot low rpm's just want to make sure...plus the engine seems to sound pretty loud..please advise if this is normal that the 05 is 300 run at higher rpm...
