i had my z for about a month. i started noticing that the car while stalled while decelerating approaching a stop light. instead of idling the car would stalled immediately. my service light came on n i got the code pull n this is what it came. P0301–P0308 Misfire, Cylinder No. 1–8. also catalyst and also this

.

I have read in several post that it can be an intake air leak, flywheel ratio, or a shift sensor. does anyone else have had this problem n who can u fix this would be amazing.

 

My Z just started doing the same thing... I cant find anything on it. Ive checked for vacuum leaks but none found.

 

Had Code P0301, replaced spark plug just that one, and it's gone atleast for now. I can actually feel the difference if that makes sense.

 

Was this happening at just idle or was it when you pushed the clutch in?

 

Both
