Well the thing is tha last week i park at the university and i let the fog lights on so natrully my battery went dead, but i mean really dead to the point that the thin that makes the engine star wouldnt even sound(i dont know the name of that part), i got a friend who help me charge my battery i conected the battery and all was fine, yesterday i got fitted mi new HKS intake it ran fine but when i got home i forgot to rest the ecu so i whent to do so, after doing so i conected the baterry and started upthe engine but when i did the rev were below 1000 rpm to the pont that the car would shut down so i think that the battery is taking to much energy form the alternator or is damge wht do u guys think?

oh yeah this has nothing to do with the intake i fitted the raight way i got sure off that

on the contrary it's definitely the new intake

i dont think that is the new intake, last night when i reset the ecu and it was give me the problem i check the battery meter and it was below the 12v, and the engien chck light dosent come on, and in the intier day the problem didnt show up

Put the factory airbox back. If this fixes the problem it's your new intake. If it doesn't it's probably something else.

What is the battery voltage while its ticking over?

Should be around 13.8v - 14.4v

fixes the problem the battery damge it was sucking energy for alternato witch was taking pwer form de the engine replace the battery and problem solve
