i have a 06 g35c and the engine seems to be making some kind of shakey noise and i don't know how to fix it. Somebody told me to try an engine treatment or oil treatment but i dont know if it will work, so did anybody experience the same thing and know if i should try the engine treatment or oil treatment and if so, what is a good kind i should use?

 

is it burning oil???

 

no i dont think its burning oil because everytime i change my oil i always check the dipstick and it seems to be fine.

 

there is a TSB on this, look it up key word is "schudder"

 

Does it make the noise while the car is running? my moms z makes a sort of odd noise during idle.. i think it needs a oil or gas treatment..

 

"shakey noise" . . . A bit vague to really offer any help.

 

+1 bro. Describe what you're feeling hearing. Is a deep rumble, sharp vibration, front of the car, rear, underneath, all over, what?

 

I just searched the forum and Infinitihelp.com and could not find the TSB.....I searched using "schudder" like you said..... Could you post a link or something....
