That's why I was thinking the temp sender, for the PCM. Maybe it's suddenly sending a -40F signal? I found I had the TPS on my Volvo shorting to 5v, when I graphed the signal.
Crank/cam sensors were put in range a year ago when it was tuned, so I doubt this is the issue. Still appreciate the help.
Yeah, that would make sense.
@Dropped88 determined that the reman PCM had an internal issue, so I sent him a used factory one to tune. Got it back today, looking forward to seeing how it does.
That, and fixing the crank position sensor wiring.
