I've tried 3 sensors now, so I'm fairly sure it can't be the sensor. Next is timing chain.. When funds allow as buying another car for the misses to get around in was more important... When the car is first started it sounds like the chain is rattling as though the tensioner isn't working though when warmed up it goes. Engine is hesitant and tends to stall when under load. So I can only assume it's this.. As also in limp mode... If anyone out there with a z22yh would like to unplug there crank sensor and tell me how it responds. Be very much helpful!
