Well, my check engine light has been on for over a week and Autozone says it's my TPS. They hooked into the OBDII port and the scanner said it was not working correctly. The part from Subaru Parts.com is $156, and I don't mind paying it, but is there a way that I can fix my existing one? I've read some of the cleaning threads, but I'm not sure if that was to "improve" a good one, or to fix a bad one. The car runs, and I havn;t really noticed anything out of the ordinary, but I want to fix it. Oh, I did notice a drop in MPG (about 3-4 MPG) over the past few weeks. Thanks in advance for the info.
