I can't even get down the block because of it! Sensors appear to be fine, bearings do not appear to be out, throttle body cleaned, coils new, had the onstar system removed too. anyone else got ideas?

Hi,

Chances are it is related to one of the wheel speed sensors even though they look good. You can check them at home. You will need to jack the wheels up one at a time. The rear will likely require both to be lifted.

Here is a link that explains how to test them:

I attached a pic indicating the locations of the sensors. Do this test and let me know the results.

Take care and God Bless,

Joe
