This isnt a pic from my car, but my car has this as well....

 

That would be a car part.

 

a dirty engine bay with alot of colorful swirly lines

 

u know... im looking for a real answer... if you dont know, then please refrain from responding.

 

I believe it is the cruise control system... but I could be wrong. :dunno:

 

the cruise control system is located in the upper right hand corner near the fuse box...... unless it has system that branches all the way opposite.....?

I do know that after u turn the car off... and open the hood... i hear it make a "pop" noise like it releases pressure a min after the cars off???

 

i'm looking in haynes

 

Nope, I take that back, it's the EGR vacuum control valve and the solenoid valve should be under there too. What it does: The Exhaust Gas Recirculation (EGR) System injects a metered amount of exhaust gas into the intake manifold, lowering peak combustion temperatures. Lowering peak combustion temperatures inhibits the production of NOx. (Production of Oxides of Nitrogen (NOx) is greatest at combustion temperatures over 2300°F.) Hope that helps!

 

Wow... that little things does that??? I don't even see one on mine! Maybe that was stolen on Sunday with the rest of my car???

 

i hear that pop every now and then after popping up the hood after turning off the engine also.
