I have a 2003 Acura MDX and recently it was throwing 2 codes P0172 and P0175.
It gets poor fuel mileage and it idles rough. 100, 000kms


Dealership says to do a valve adjustment but I highly doubt that that is the issue.

Anyone encounter this issue and what was the fix?

I searched a bit on the net and it appears that there was a recent TSB for it NHTSA No.: 10021343 listed on April 17, 2007 for something similar that was related to engine cooling and what not.

Suggestions anyone?

Thanks
