Sounds like it needs to warm up a bit more. I have the same car with 214,000 miles. The rings are starting to wear and the compression is dropping a bit, especially before it reaches operating temperature. Slightly heavier oil, a little more rpm on initial startup (gas pedal) and wait a whole minute before loading the engine, either with AC or by driving.

Clean spark plugs help a lot, too. They don't have to be brand new, but a little DIY plug air blaster from JC Whitney really makes a difference.

Enjoy,
