With regards to the smoke, you can safely go on your trip, with regards to your check engine. Be careful.
Here's a few tips that might help: Clean your MAF sensor, take it off and clean all the electrical components with an engine degreaser.
2nd: change spark plugs and spark plug cables (changing cables prevented me from throwing my car to the wreckers. It was making a laud knocking noise, and it stopped after that)
These are the cheapest and most effective measures.
Also. The most common problem for check engine light is the oxygen sensors. You might need one or 2 depending if you have 1 or 2 exhausts. U can pick them off ebay for like 20 bucks a piece.
Let me know how it goes.
