With the scan can you tell me which codes they are, here is a guide to help:

I have seen a bad turbine revolution sensor cause problems like this, here is the location of the sensor so you can swap it out if a code is stored for it. Check out the images (below). Please upload pictures or videos in your response to the problem so we can see what's going on.
