My Ride: has a D-Pillar
Good! I have a lot smoother idle as well....but an issue has emerged since i seafoamed:

My MPG has gone down to about 22. This isn't crazy low or anything, but I usually get 25 in mixed driving. The fact that I only got 350 miles out of a tank makes me upset. This was the first tank after I seafoamed and changed my oil. Hopefully the next one will be better.

I am thinking the issue could be:
1) Spark Plugs
2) O2 sensors (although no codes were thrown?)

Anyone else have thoughts?

I am going to do my Valve Cover Gasket and VANOS within the month, so it should be interesting to see how that will effect my MPG.
