Replacing the Throttle Body Assembly on a 2006 Chevy Cobalt

[fs_tigre]

Hi,

Every time I stop my car it start shaking so I decided to take it to the shop and it was diagnosed with a bad Throttle Body Assembly and I was wondering how hard it would be to install it myself.

How hard it would be to install it myself?

Apparently this is a dealer only part and costs $270 and I was wondering if there is a well known online auto part that could have this part?

Any online auto parts?

Thanks a lot!

i paid 70 dollars for a brand new GM 2.4L intake mani and TB. shop around, 270 is way too much

Thank you all for your help.

One more question.

What does the Throttle Body Assembly do?

As I said, I took my car to Merlin’s and they told me it was the Throttle but I’m wondering if it makes sense according to the following symptoms , the car shakes when I’m stopped, but it runs just find once it starts moving.

Thanks a lot

It could be having trouble getting closed completely so I wouldnt count it out

The throttle body takes air into the engine. Your air/fuel ratio is probably messed up at low rpms
