ok well i finally got around to half way hooking up my nitrous kit.. anyway the car was running fine before i started...now i cut the fuel line to the fuel rail to put in a T for the fuel slonoid. (no leaks) i also drilled a hole in the intake tube about 3inchs way from the mani. i didnt put in the fogger caz i need to hook up the nitrous side tomorrow.. but now when i go to get on the car it sputters from 3500-4500 sounds like detonation. is this because of the hole in the intake tube missing with the vacumm.. i dunno i can figure it out...fucking coil pack obd2 shit

 

Unmetered air getting into the intake tube would definately be suspect. Plug the hole and see what happens. Nothing else you did should be causing this.

 

i will assume that is the problem but.... do u think that i will have a problem spraying on the manifold side of the maf or should i put the fogger on the filter side.
