3800 engine starts and idles great. try to give it power it stumbles, coughs & sputters & fires back thru throttle body. Will not maintain fuel pres. when engine off key on. pressure holds great @ 38+ with engine running.:jerking:

Tough to diagnose from a distance, many things can cause this, MAF is the most common.
