well first off let me say that i am brand new to this site and i finally got my 240sx. well i got my 240sx for $600 and it has 170k with at rebuild motor that has 20k on it...so you do the math...the call is great i love it EXCEPT in the moronig or when i first start the car SOMEtimes the car boggs a lil very lil....and in the moroning i let the car warm up and everything and then i got to work but once in a while the car die on me like i see that rpm got to 0 and off it goes. i see the filter(they plugged in a cold inake filter to stock hosing) is in need of replacement and they said they did a tune up but i am still gonna do it on my on ...i work auto zone so i just get what i need .... hehe..... but i want to know is thet anything like a sensor that coulkd be causeing this ? because i have a an integra and that thing always had problem with sensors so i thought maybe this is the same (yes and am a G2 tegger as well but can you blame me honda is the basic platform)

 

wow 20k? thats amazing, anyways you say they put a intake on it? check the MAF

Try what they said and if that don't work see if any codes are being thrown by the ECU.
