Ok i have been chasing this problem for the longest, finally got it to throw a code.p0335 crankshaft position sensor circuit. I replaced the sensor and the car still throwing the code,bucking and shutting off at times. cars also running really rough. Any suggestions? thanks in advance

 

A bad crank sensor does not cause those symptoms, afaik. Maybe one of the cam sensors is bad. Cam sensors are known to go bad, of course. Maybe the replacement sensor is bad, too?

 

Thing is it keeps throwing a crank sensor code. I replaced one of the cam sensors about 3yrs ago, but i can't recall which one it was.

 

Check the wiring very carefully, at the connector and follow the wire back to the main harness. But a lot of people seem to have problems with non-Nissan sensors.

 

cam or crank sensor harness?

 

Ok I found a dead coil was my problem for the rough idle. Replaced the coil and now that problem I s fix. But I'm still getting the crank sensor code and the car starts breaking up at around 4500-5000 rpm. Anything below that car seems to run fine. I'm all out of suggestions.
