[QUOTE="hjpcummins, post: 537599, member: 3207"] Some know a little history of my 5.3. Pretty much full rebuild besides heads A Little info on engine 01 5.3 0 miles , cam & springs, psi harness and ecm. While driving around the yard I can cruise just fine, after 1 or 2 half throttle pulls it starts to run like complete dog ****, damn near just falling on its face and shutting off. So shortly after I just let it sit and idel to test the new water temp gauge and try to get air pockets out of the system, during that time the idel is just stumbling. Oil sits at 40 psi at idel (fluids checked) Vacume leaks checked Fuel rail air bleed And so on.. This happened last time I had it in the yard, Parked it and started researching for someone with similar issues,with not much luck. Scanner didn't find any trouble codes Just looking for a little advice. Thanks [/QUOTE]
