Miles should make minimal to no difference whatsoever of what the motor is capable of, Several of the faster cars on this site have over 200,000 miles or darn close to it.
If you notice the car is slower or does not perform as well as it used to, there is likely a problem or several problems causing this.
Start with Plugs, Wires, Fuel Filter,Air Filter, fix other nagging problem with your idle, etc.
Then order a throttle body gasket, remove throttle body, remove sesnors and clean the heck out of it till it looks new, you can remove the maf sensor by carefully using rubbing alcohol and a q-tip. You can clean the IAC sensor (little spindle motor thing) with TB cleaner as well and wipe it down with papertowels or whatever.
If your fuel economy is still below what it should be (30mpg highway) look at replacing the o2 sensor WITH A DELCO..bosch are crap for these cars.....
Basically start with a full comprehensive tuneup, after that if it still is not what it should be you may have a failed component somewhere but lets get to the basics first.
