I need some moral support as I'm at my wits end.
The 7.9375v reading just seemed suspect, as looking at the log again it never changed.... just gave the same number the entire time. That number should have fluctuated during the log, so I e-mailed SCT and they confirmed I should see fluctuation. Checked the PID for battery voltage through the X4 and got within one volt of what was measured at the battery. I also double checked the CCRM PIN 12/24 (PCM POWER) and after trickle charging the battery over night got 12.2v at each, so I must have not gotten the leak far enough in...
So recap:
Fuel Pressure is 30 psi at KOEO, 35 psi at idle, and 45 psi with vacuum line detached.
New Fuel Filter
New NGK TR6 gapped at 0.030 (will be pulling all tonight to check gap again)
22 inches of vacuum at idle
No Check Engine Light
No Codes, PCM seems fine in this regard because unplugging the CCRM generated code P1000
Tuner said I needed to replace the stock ignition coils, which I'm fine with... but only if that solves my problem. I think I'm going to get an in-line spark checker from Harbor Freight. Certainly open to any other ideas... I'll get some video of idle tonight as well.
