Ok so i just got a SES light finaly so i could get it scanned and figure out whats wrong. Went to Auto Zone for a code scan and my "Throttle Position Sensor" craped out. I can still drive the car fine but i have NO power. So my question is..... #1 is it safe for the engine to be drivin to college and work with out hurting it? #2 Is it something i can do my self? And i need links to the best brand TPS so i wont have it crap out again for a long time
