ive been getting a slight fluttering under light throttle
almost like im running of gas,only happens under light throttle
like in traffic ,only when the pedal is held steady,as soon as u give it more gas its fine,i tried changing the fuel filter but its still there.
im guessing maybe a bad plug,i still have the stock plugs?

 

Mine did the same thing until I replaced the EGR Valve and EGR controller module.

 

sounds like your EGR...

 

i only have 12k miles is that normal
for the egr valve to go already?
