The definition says: Throttle position sensor (TPS) 1-2 correlation

Probably cause: 1. Poor electrical connection 2. Failed TPS

We were talking to the guy at O'Reilly's when a mechanic pulled up that the worker knew. We got him to look at it. He said that the TPS was dirty and we could TRY to clean it... but he doesn't know if that will work because of the code that it's throwing is saying that the sensors aren't agreeing. He pulled out his laptop and used the program that they use at work. Basically that program said that you can't change just the sensor to actually fix the problem for that particular code.

The check engine light was blinking this morning on our way to the university (about 8 miles). Then again when we left the university to my fiance's work (a little under a mile), and yet again less than a quarter of a mile to a book store. But then when we left the bookstore, the light did not come on at all on the way to auto zone (about 5.5 miles), then didn't come on when we crossed the street to go to O'Reilly's (literally right across the street), or when we drove home from there (about 3 miles). When the light would blink, the car's rpm's would flucuate above starting and the car would sound "loud", but when it didn't, it sounded "soft"....

Any ideas? Is this hurting my Catalytic Converter? Do y'all think this could be my actual problem? I'd really hate to have it fixed.... and that not even be the problem. What would y'all suggest?
to put it bluntly, an active misfire is sending raw unburned fuel into the catalyst, and eventually it will render the active elements in the catalyst unable to do their job, and if left unchecked, will cause the converter to clog up and raise the pressure in the exhaust system to where to car will run even worse. (and if your Area does emissions testing timed with your vehicle registration Renewal, your aveo WILL FAIL, and will probably prevent you from legally driving your aveo until it gets fixed.) and when I said wires, I meant the Spark Plug wires attached to the Ignition Coil Pack. and there's a few people on here that have had the P2135 code come up, and they had to replace the entire throttle body (2006 was when they changed over to Electronic Throttle Control, meaning there is no physical link between your foot, and the throttle body; its all done electronically via an Accelerator Pedal Position sensor sending a signal to an actuator on the throttle body, opening and closing the throttle valve, which dictates engine speed.)
