Mechanic at Firestone said he has to replace the entire "throttle body" for $600. Is this unreal or what?


Asked by Dec 09, 2013 at 07:14 PM about the 2005 Saturn ION

Question type: Maintenance & Repair

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.

that's possible on some cars they are weak,but not able to work around. the vacuum seals around the plenum under this part would be suspect first, or a used for about 125 would a quick self fix if that's the failed part.

Very rarely do you have to replace a throttle body. You can clean them of carbon. But I suspect it's the throttle position sensor that is the problem. It's attached to the throttle body, so that maybe why they want to replace the whole assembly. The part is around $75. add 1/2 labor. Tell your sister to find another place to take the car.

3K......cain't be worn out.....another prob. Mass Air Flow maybe.


Go someplace else I find it hard to believe that it has a problem with that low mileage, it could b a fuel supply problem, with mileage that low there could be a lot of moisture in the fuel system.
