Hey everyone, I have a 2003 cts with the 3.2 motor, like most people I have a problem with my throttle body and can not drive my car. Its been well over 5 months and the part is still on back order from the company and GM has done nothing to help me out. I was wondering if someone knew if I was to purchase a throttle body and manifold off of a 2004 and up cts would I be able to swap it out and have my car running. Any help is much appreciated. Thanks in advance.
