My Cobalt SS is getting up there in years and miles, and recently I’ve noticed that it isn’t performing like it used to. It hesitates off the line, and legs a bit when I want to accelerate sharply. I’d really appreciate some suggestions on how to get it back into shape. I changed the spark plugs, but the difference if any was very minor. Would less gap in the spark plugs help? Thank you! ---

Maybe try an injector clean and cleaning the MAF sensor. I assume you have changed the necessary filters. ---

Start with a compression test to get an idea of the health of the motor. ---

Try cleaning the electronic throttle body. ![image](https://global.discourse-cdn.com/cartalk/original/3X/f/e/fef836719ab3b2e4dbbe707f6236b0df58725262.jpeg) Tester ---

All good suggestions. I’d add a faulty throttle position sensor. ---

Electronic throttle bodies don’t have TPS’s. Instead, they have accelerator pedal position sensors. ![image](https://global.discourse-cdn.com/cartalk/original/3X/7/8/78dd0df3e93cac90790a7e80f1088ebc9e0acfe3.jpeg) Tester ---

Right arm! I’ll start with the compression test and fuel filter replacement. Many thanks, everyone! ---

It was changed sixty - eighty thousand kilometers ago. Still in good condition ---
