well ive been trying to hunt down the cause of my surging and stalling. its only throwing one code, p1391, intermittent loss of cam or crank signal. both of which have been replaced, to no help. ive noticed something weird though. if the crank sensor is unplugged, engine will just crank and not run at all, as expected. but with the cam sensor unplugged, it makes zero differnece. engine runs equally shitty either way. and with a brand new sensor, id think it were bad wiring. but when it is disconnected you get a new code. cam sensor circuit malfunction. so it does realize when you unplug it. but it runs no different. can anyone make any sense of this? thanks
