Noise from engine 1997 Tahoe 5.7

5.7l Vortec Distributor Timing
I just installed a new Bravex Distributor in my 97 Yukon GT 5.7l Vortec after doing the MPFI upgrade. I fiddled around long enough so the distributor body sat somewhat parallel to the intake, and there was no more P1345 code. I got an OBDLink MX Bluetooth scanner with Dash Command App installed...- YukonGTmaster
