Fixed. Read my last comment.


Just got this car one week ago, and after changing the oil this new sound decided to grace me with its presence.

Engine bay recording.

Interior recording.

My co-worker thinks that it is the valve train.

What do you guys think?

Any help would be greatly appreciated.

 

its so hard to tell over the computer.

do you have a mechanics stethascope? it will help you pinpoint the noise.

More information that may be useful.

Just replaced IAC right before the oil change; had an extremely hard time removing old one and installing the new one. Just checked it, and it is only hand tight. Cannot get any tighter with my channel locks.

Appears to be running rich as well.

Could any of these issues cause a noise like this?

Or - replacing the IAC require proper adjustment? I was thinking that it was a simple remove the old and slap on the new.

 

Fixed!

Here is what happened.

After getting this and knowing how old its oil was, it snowed and iced over. So it was taken to a local oil change place just to have it done as quickly as possible.

Who ever was filling the engine with oil accidentally knocked a plug wire off and didn't notice.

Took me a few days to figure this out, but all is well and happy again. The oil change place is giving me a $20 credit for my next visit. Not that I plan to ever let anyone touch this call like that. However this $20 credit will be useful when it is time to purchase my wife new winter tires next year.
