Mechanic at Firestone said he has to replace the entire "throttle body" for $600. Is this unreal or what?
My sister just had problems with her Saturn I think it's a 2007. Bought from mom's lease with 3,000 miles on it. Has had lots of problems. Now on a business trip the car wouldn't accelerate. She could only go 50 miles an hour on the interstate. and it buck at idle.
