any thoughts? its only noticibile around idle. it fluctuates with revs, while moving or while stopped. it seems worse when warmed up, and almost non existant when cool. it comes around the far right injector area. doesn't seem to be intake or vacuum. i know its a shot in the dark anyone could guess what it was. i use a hallow tube to narrow down where sound comes from and like i said its around where the far right injector is (looking from front of car) i tightened all intake mani bolts to make sure it wasn't an air leak. could it be internal like water pump or timing belt or tensioner? any input very much welcome, the noise is driving me bonkers. (more so)

thanks in advance

I don't know how the tbelt or tensioner would cause I whining noise, but that is what a water pump will do when the bearing starts to go...

if im not mistaken the timing belt will make a whining noise if it is too tight, i have to replace my auto tensioner with a manuel 1 to fix my problem. Timing belt is my guess

it seems to only happen after warmed up. its comming from timing belt side, but i put a scope to timing belt cover and its quite. it comes from around the intake or fuel rail. is there anything in there that would whine or whirrrrr after warming up?
