sounds wierd ?
My grandson used my o8 for a few days, he said it sounds like the motor is going faster than it should. the rpms are around 2200 at 60 mph but the motor does sound like it is going faster than it used to ANY suggestions what it could be?

HHR's run at approximately 2,250rpm at 60, so yours is right where it's supposed to be.
That's assuming you have an automatic, if you have a 5-speed I'm not sure what rpm they pull in top gear.
I'd check the exhaust, or have it checked, you may have a leak in the flex pipe from the exhaust manifold to the catalytic converter. When they let go, the engine note can become quite raucous.
If you have a manual trans, check for a slipping clutch.

If its the flex pipe you better drive with the windows down, and it will get worse, I bought my flex pipe from Rock Auto $35.99 plus shipping had it installed at Midas $90.00 its all good now, good luck.
