Read the full transcript

Here are the signs that the throttle body is going bad on your Buick La Crosse, 2006 to 2009, 3.8 liter V6 engine. Number 1, unstable idle. The RPM dips, surges, or the car almost stalls when you stop. Number 2, delayed throttle response. You hit the gas and the car hesitates. That's the electronic motor sticking. Number 3, random reduced power or trashing control warnings. And these 3.8 liter cars a weak throttle body trigger limp mode even if you don't have a clear code saying so. Number 4, light surging at a steady speed. So if you're on the highway and the car feels like it's gently pulsing, the blade in the throttle body isn't holding a steady angle. If you're seeing any of these symptoms on your 3.8 liter V6, check the throttle body before checking anything else. Also, I do carry verified OEM throttle bodies in stock.
