My Terraza acts like the accelerator cable is sticking. on 2005 Buick Terraza

Monday in a light rain on an incline, I could not get the car to move without spinning the left front wheel. I could not get a gentle start. With winter approaching, this could prove dangerous. Does this car use a throttle position sensor instead of an accelerator cable? What is involved in replacing the TPS?

That engine doesn't use a throttle cable, the throttle housing has a fully electronic unit that incorporates a throttle control motor, throttle position switch all built into one unit. I just looked to see if there were any recalls or service bulletins for the traction control system but there aren't any I see.I would imaging there has to be a problem with the traction control. A Buick comparable scan tool would be needed to look at the ABS, traction control ect... to see if there are faults.

Thank you, There was a loud clicking noise each time the tire spun. So, I need to have the traction control checked.
