[DJJOEY1976]

Check Engine Light Comes on Car Shakes and wont go past 10 Miles Per Hour. I shut the car off and wait for like 5 to 10 minutes, start it up again and light stays on but car runs great. After a few days the light goes off and stays off for a week or more that the cycle repeats all over again. I have new plugs and coil. It's s 2009 AveoLT with 50,000 Miles. Please help

Thats for the response Justice. I went to Advanced Auto and they look into the code. I don't remember the number, however they told me it is showing the Throttle Position Sensor. Where is that even located and how do I change it?

Im not sure as I've only had my aveo for a few weeks. But some simple research should point you in the right direction. Have you purchased a DIY repair manual such as Chilton or Haines? Those are a great source or information.

If you got a throttle body position sensor code you're probably going to need a new throttle body assembly. It is sold as one unit and its known to be a part that can go bad.

Is it easy to replace? Where is it located? Do you have pictures? Thank you

Before hanging on any parts, I would first try to clean the throttle body with sensor-safe throttle body cleaner, and the tip of the TPS which is located inside of it. Best to remove the TB in order to do the most comprehensive cleaning.

The throttle body is the next metal bit inline after the rubber hose that connects to the airbox. I've circled where it is on the picture below:




It looks like this:
