Did you tighten your gas cap fully when you got gas? If not, your computer noticed an evap leak, and that triggered your check engine light. You will need to get it cleared, or wait approximately 40 ignition cycles. I suggest you have it scanned, and let us know the codes. As far as the shake, thats a different issue, and would not cause your CEL to come on.
