ok hey guys this is my first post here n i was just wonderin what u think is wrong or if u have the same trouble...ok when i start up my car in the mornin (or when the engine is not warmed up yet) i get a sorta loud sound commin from the engine...its hard to explain the sound but its not the normal engine sound...it sounds rougher but once its warmed up it doesnt make that noise...anyone know whats up? thanks!

 

if you have an aftermarket intake this is very very common, nothing to worry about, kinda sounds like a duck for a second right? I get that too, and have been told by alot of people the same thing i told you

 

Try to describe the sound. Is it a squeal? Is it a rattle? Is it a knock? Does it sound like an animal? Is it a hiss? Does it screeeeeath? Buzz? Honk? Chirp?

Approximately where in the engine bay is it coming from? Left, right, middle, top, bottom, front, rear..??



More info please... we'll do our best to help you.

 

umm its hard to describe but it sounds like the engine is much louder....any help?...i really hoppe its not like my valves or anything...thanks guys!

 

Hey NavyMax, buy your nick i'm assuming that you are in the Navy, but I could be wrong, if so where are you stationed?
I'm in Great lakes RTC

The noise is normal, cold metal "shrinks" thus making more noise,
but as longest everything is nice and quiet after it gets worm
you have nothing to worry .

Nick

 

hey nick....nah im not in the navy...in my name its meant as navy blue....but obviously u r in the navy and hopefully u wont hafta go over to iraq man...k thanks for the knowledge bout the metal i never thought of that thanks again!

 

my engine is loud in the mornings too.. sounds like air is coming from under the car also. normal for me.. i guess =)

 

Is the noise a loud gtinding noise that stops after a couple of seconds? If so it is a common problem that many experience with these models . others have tried many things. the only thing that worked for me was replacing the starter. After that the grinding noise stopped. But try looking for other messages on this board regarding starting problemsor cold start problems. You should be able to pull up more info.

 

open up your starter and throw some lube on it.. i know theres some howtos around here somewhere... thats probably your grinding problem right there

 

i was about to post the same question until i read this thread.

mine makes a loud squelling noise.kinda like when you hould the ignition to long but thats not it.it will squell for about a second and the car will idle ruff and the shut off.only does this in the mornings.but if i just turn the key half way for a few seconds it wont do it.i wanna think its my fuel pump not preasuring the system enough or maybe i got some dirty filters.hopefully its not the pump.


o and im navy.stationed in jax florida.hows life pushing boots.

 

nothing is wrong with any part of you car.
maxima's are programmed to run rich on startup until the engine is warm. everyone's maxima will idle high (engine will be louder) until the engine warms up and the rev's drop.

diggytdog, your starter needs to be regreased.
