Has your car been running fine up to this point, then suddenly these symptoms? Could be you've got a problem with one of the fuel pumps not running. That could explain the lower system pressure and rich when running beyond idle. Could be that, maybe not. Confirm that both pumps are running, you need to get your system pressure where it belongs. And slap in a new fuel filter, just in case it's plugged with sludge.
I'm not too clear on your cold CP's. They should be around the low 2.? bar (would have to look up the specs), then rise within a couple minutes of plugging the power connection back in. Just because the resistance of the internal heating element is ok, doesn't mean it's heating up. It's fed power via the rear fuel pump relay....could be a common problem. Check to see that you're getting voltage at the connection (pumps must be running).
