2000 LX F23A1...

only noticed it today but when I go WOT it stutters around 4K... I previously ran a 75 wet shot of nitrous in the summer but has since removed it for winter... I am still running colder plugs though.. could that be the reason?

what else could it be? dirty throttle body? injectors?

oh and what's the proper gap for the spark plugs?

 

****.. it could be numerous amount of things.. pull out your injectors and see if they are dirty.
