i think it's coming from the driver's side. i cant hear it that well, im terrible at things like this. i had the intake tube off a few weeks ago replacing the wires. i'm not sure if or when i'm going to be tearing this apart. i want to keep it, but like i said earlier, i don't think i have it in me to fix it. i love the car, i've had it for 6 years, but it may have reached the point where it's beyond my ability. i need a daily driver, but i am broke. probably end up on my motorcycle every day.
