Have you tried using a scanner to see if it's giving any codes?
You can try pulling the engine cover off and checking the plug wires. See if they're loose, worn, or cracked. Also check the coils for cracks on the front and back of them. Just unbolt them one at a time and inspect them.
Your seal for the MAF sensor might not be on correctly and water might be getting into the throttle body. The seal is on top of the intake housing. Try putting a little silicon grease on the rubber seal to make it seal better.
Your best bet is a scanner though.
