I ran the Concept Z software on my Z. Here are the results. I'm not a mechanic so if anything looks abnormal please let me know. Mas Air/Fl 1.5V Air Flow 17 CFM Throttle Pos 0.40V IACV-AAC/V 90% IGN Timing 354 BTDC Battery 13.76 V O2 Sen-L 0.32V Inj Pul 2.41 mSEC A/F Alpha 109% A/F Alpha-SEL -9% O2 Sen-R 0.31V Inj Pulse 2.27 mSEC A/F Alpha 100% A/F Alpha-SL 0% The vehicle didn't have any ECU codes other than an Engine Temperature Sensor 4 starts ago which I think the connector was just loose and was solved by me securing it down. I ran the power balance test, when it dropped the first cylinder the car bogged out and stopped. The car has bogged out more than a few times now (not just during a power balance test) and every time I'll go to restart the car afterwards and it will have a strong crank but will not turn over or even sound like it might turn over, almost like it's not getting gas. However, prior to the plenum pull I did remove all old gas, cleaned the tank and installed a Walboro Fuel pump which I tested and was working well before the pull. I am going to run a boost leak test on the car next. Any other tests I should be running?
