Presuming you are saying all the coils, injectors and plugs have been replaced I'd test the crankshaft and camshaft position sensors.

i bet u anything that your car is backfiring from your intake when u flood your gas pedal. im 99% sure that u did not use the original spark plugs, if im correct then thats what u need to replace.

Again, I am presuming you replaced everything you said you did with Nissan OEM parts (i.e., plugs and coils). The camshaft and crankshaft sensors should throw theri own codes if bad but may not if intermittent. Also, there is the possibility of your electrical harnass having a short in it and it can be tested. You cheapest assistance in testing these is to purchase a Haynes serivce manual for your Max at i.e., AutoZone for $14 and go from there.

i got the book, but i'm still having the same problem i can't figure out what is wrong. how you check the wireharness? you mean the plug? well i use OEM coil, and OEM injector but the spark plug is from auto zone NGK the regular one. but i also put back my oem plug it still missed fire. some reason there are power to the plug but nothing happen. car run like ****. if there is power to the plug? do you think there might not be ground? i'm not sure because i just brought this car like this.
