OK, so I start the car this morning and I look down and see a little red check engine light on... and Im sitting here thinking, I have never seen this on before.

I also nothing that the car seemed to be idling a bit high... ie 2000RPM. So as I stair at it thinking, damn I have to go to work, and I am already late!! I tap the gas and it goes away... so thi leads me to think its teh Throttle Position Sensor...

Am I right? My car has also been idling a little rough as well... would this contribute to that?

How much and how easy to do on your own? Keep in mind I used to fix jets for the Air Force, so I know my way around tools...

Run the self diag first, to be sure. I'm thinking it may just be an O2 sensor, The rough idle may be simply due to a dirty throttle body. Do the diag first, and take it from there.
