My dsm is making this weird rattling/clinking noise while driving...it seems to make the noise when say if ## not going fast enough for the gear your in...if I'm in 5th and only.going 35-40 it starts making the noise...any ideas?

You're lugging the motor by driving too slow for the gear that you're in. The rattling noise is knock...a lot of it. THIS IS VERY BAD! It's damaging your motor. Drive in a gear that keeps the rpm's up above 2500. Use only Premium gas for the higher octane (probably 92 in Ohio).
