2004 Z71 Tahoe shuts down at the light

[dion165]

Can anyone help me with this? My 2004 Tahoe shuts down at the light occasionally. I have no code to tell me what is going on.. A friend said this vehicle at times suffers from the throttle body sensor. Would this cause the car from shutting down? I gave it a full tune up. I am not sure what to do next.

Thanks

It could be the throttle position sensor, maybe. Try unplugging the sensor, cleaning it, making sure it is good and dry and adding some dielectric grease to it to ensure a good signal...

It was indeed the throttle body. i cleaned it and it worked better. I also picked one up from the JY and that works perfectly also. Thanks All
