The fuel injector is separate from the throttle body. Check the ignition timing. Check fuel pressure, key on, engine off and engine running.

Checked fuel pressure is good to the injectors from the pump and throttle body is clear of debree and still put it in gear and give it gas chuggs bad and restricted fuel. But when it idles it runs great. At a brick wall and don't what Would be causing it had 2 other mechanics working on it to and they know there stuff and other suggestion or know of any that has had this problem

amber87, check the compression, check and clean the EGR valve, and check for vacuum leaks.
