Strange Idle *VIDEO INSIDE*
 

Alright, so I don't normally post these kind of things, but this is getting confusing.

I've had a rough idle for as long as I had the car (about 2 years)

Changed the wires/plugs/etc. Doing so lessened the roughness, but it was still there.

This isn't really the issue, cause it's most likely the mounts from the searching, but it's this noise I'm getting at all RPM's. I believe someone called it marbles in a tin can kind of noise in an old thread?

Now I thought this was cause of a blown ebay "Oem Spec" midpipe I had. That with the sulfer/rotten eggs smell was happening. So I installed an OBX test pipe to let me work my way up with what's going on.

Bad odor is gone, but this tinny sound is very loud now, it came to my attention when I left it on, and it was very audible, along with a really bad dropping idle.

So when I arrived home just now I took a quick video off my iPhone. As you see the idle as far as the cluster shows is fine, the noises, not so much in my opinion. The constant popping may just be cause of the test pipe, but I recorded it anyway, but when you see me move to under the car pointed towards the manifold area, you should catch the loud tinny sound.


WARNING: Lower your volume especially if you have headphones
