I have a 95 240sx stock ka24de. My car idles and revs fine. However under acceleration/load. begins to like stall/sputter, and makes no power. it accelerates fine just makes no power. Timing is on the money. I did a complete ignition tune up. and it helped, but now when i checked my spark plugs and the motor is running lean. I have 2 codes, knock sensor, and crank position sensor. Haven't changed fuel filter. But the car would run fine sometimes. Now its a permanent problem. Anyone have any ideas?? Ive searched the web and can't find anything.
