Does anyone know where I can get a schematic diagram for the underneath of a G Coupe? I just came back from dinner and I have something dragging underneath making a racket. Its located in front of the rear drivers side wheel, there is a matching one on the other side, looks like some kind of protective pad. The weather is too miserable for me to jack it up and take a look. It doesn't look like anything serious.

 

check it out...

 

There is a small Plastic diffuser in the area you described I dont think its shown in the picture above I think a few 10mm bolts hold it on.

 

I think you are right. Thanks!
Thanks also to 35Bills.

 

The cars with the aero package or M6's are a bit different with additional diffusers underneath. I've got a few that don't appear to me to be in that picture.

 

Here is the offending piece.

 

I thought that would be the one! My entire front plastic cover ( the big one that is under the engine) fell down last night and drug on the ground I was about 20min drive from home when it happened so there is not much left of it.

 

You should be thankful!
There was a white marker pole with the black top in the middle of the road. Cars all around me so I hoped I could clear it. Long story short, the metal base of those post ripped open the big plastic cover, ripped off the small one, and bent the crap out of my flex pipe.
