I removed the valve cover to get to the springs and for laughs I also snapped off the PCV valve while working on the catch can. Bolted everything back up to drive to O'reilly. It clearly wasn't running all 6 cylinders, was shooting oil out of a place that, well, was already leaking a little but damn it was really flowing (there is a dark line from my driveway to O'reilly), and gave codes for 'cylinder 6 injector circuit open' and a misfire in 6 obviously. Oh and I had assumed the exhaust flange needed a gasket because it sounds like a diesel but apparently the connection between the exhaust pipe and manifold has a hole. I found that out because it got louder.
I first thought it was increased crankcase pressure forcing the oil out, but that would only make sense if the PCV valve was actually installed and wasn't breathing right - there was just a hole at the moment. Drove back, installed the valve, didn't make a difference. I swapped the plugs for injectors 5 and 6 to see if it was 6's plug or the injector itself, then it gave codes for 5 and 6 'injector circuit open'. Switched them back and both codes stayed. So, 5 is bad now too. Thinking that 4 must be ok, I switched plugs 4 and 5 to see if maybe 5 would act right. No change and no code for 4. Put in new 5 and 6 injectors. No change.
Anyway, wires were good at both ends (from injectors to PCM). No rubbing, no ground, voltage was even to all 6 injectors. However, when testing the wires coming out of the PCM, there was no pulse. Driver's weren't communicating with the injectors. When I unplug injectors 4, 5 and 6 there is no change in idle. The IAC doesn't compensate at all.
My idle vacuum is down from 15 to 10, presumably because I'm running on 3 cylinders.
I used rope in the spark plug ports while changing the springs so, maybe a couple of them didn't thread right?
Maybe I... I got nothing other than it's the PCM (I've only had it 3 years)
Any advice guys?
