Check Engine Light after Oil Change

I have a 1999 C2.

About 70 miles after changing the oil in my car with a mix of 5-30/0-40 Mobil 1, my check engine light came on. Ever since I changed the oil, I have had some idling issues as well. When idling, the car will go through a few periods of revving (always below 1K), and then it will eventually settle down and stay idle at a specific RPM. (This usually takes about 3-4 cycles before it settles down.) Same is true of my oil pressure gauge -- it moves around slightly when idling instead of cycling like my rpms.

Right after changing the oil in my car, the car came up clean but it had a lot of problems idling... worse than it is now. After some driving, the hard idling went went away -- now I am left with the "cycling" that I describe above.

I have check the oil level and the oil cap (it is on tight).

I also am sure that it is not the MAF as I replaced that recently (few K ago).

Any help would be greatly apprecited.

Thanks!
