It is what it is and I try not to think about it. Car currently has 134K miles on it and is 14 years old. I have not noticed any power issues, car still pulls well through that rpm range. No plans to do anything about it.
    You'd be surprised... my car rattled since I bought it (65K) but I could only hear it when all the windows and sunroof were closed. I didn't think I'd lost any power until I replaced it with a Dr. Vanos unit... regained 2.2MPG per tankful, and definitely felt the power at the lower-end of the RPM band... you might want to consider it.

    Well, I still get 31mpg on the highway (6th gear, 70-75mph) and get 23mpg combined. Maybe there is oomph missing on the low end but since I am not racing the car, I'll never know.

    If my engine were going to blow up (like the cooling system) I would do it, but since there doesn't seem to be anything fatal on the horizon, if I can't do it for less than $300, it just isn't worth it to me. Don't mean to sound cavalier about it, but it just isn't that important in the whole scheme of things.
