Intake Mainifold Carbon Build Up Cleaning *Pic Heavy*

ecrew,

While you have some downtime waiting on some parts. I'd get some Mass Air Flow sensor cleaning and clean the MAF sensor and also clean the throttle body. I'd also do a throttle body alignment when your all done.

Another thing I'd do is change your spark plugs. I think I read you have about 60k miles which would be a good time anyway. I checked mine today just to see if they were covered and they weren't. They were actually pretty clean.

Oh, and I noticed your upper intake manifold is different than mine. I know you have a 2008 but I didn't realize they changed that part, interesting. It also looks like it's made of aluminum? Mine is plastic and looks smaller, from the photos.

Interesting because you mention PCV breathers from both valve covers. I just went and looked at my engine I have one on the left side of the car connected and the right side has a cap on it, this is all factory. Wonder why they didn't connect both sides to the PCV?

Interesting, same with mine.

Good call on the cleaning. I don't want to change my plugs until a week after I get my engine all back together and all the the carbon deposits have left the building. Some of the deposits fell down the open valves and some are still in weaker states in the valves.
