One thing want to address is the air filter I put in it. I've read that your not supposed to use oil based air filters for the sake of not ruining the MAF sensor. So the only dry filter I found for the car is some shifty 11 dollar off brand that may also contribute to the engine not running at 100%
That noise could possibly be the valve lash (for lack of the right word) lifters, our cars use oil filled "lifters" normally they fill with oil and they stay full even after shutting down but after long sitting they do drain.

I have used seafoam many times I think it is wonderful stuff, put a few ounces in the oil and run it no more then 50 miles is my personal recommendation, it will clean dirty gunky oil passages. Also be sure to use it in the vac system to clean the tops of the valves and the intake track from any and all oilly gunk. then put a small amount in the fuel tank it acts as both an injector cleaner and additional carbon deposit remover.
The problem with oil type air filters is too much oil (user error) will allow some of that oil to coat the maf sensor as its pulled through the system.
I believe I mentioned this before but the gunk in the air intake is from the pcv system not much you can do about it other then to make catch cans or just let it vent to atmosphere.

When was the last oil change before your oil change 1k miles ago? it may need a shorter oil change interval while it "cleans" up the engine.
