I was look at my throttle body and I notice I have oil in it. There was a little bit where the intake connects to throttle body. What does this mean?

Blowby from the passenger side PCV circuit is where this generally occurs. Fixes run from cheap & simple to expensive & complex. You'll need to thoroughly clean the TB and IAC valve. Double check the stock elbow & hose. Any (vacuum) leaks create unmetered air conditions which can, in turn, decrease efficiency/mpg.

Yes. With a LEAKDOWN test, NOT a compression test.

Most engine diagnostic starts with a compression test and goes towards a leakdown test. Most of the time I go right for the leakdown. Its more conclusive and definitve.

To the OP, it blowby, or a faulty pcv valve/crankcase evac system. clean or replace the pcv, find and eliminate any vacuum leaks and clean the throttle body and the IAC as directed.
