It's showing a p0660 code. So, I believe it's a vacuum line messed up somewhere causing the tunning valve not to open and close properly. Which is causing it to bog.

P0660 code problem with bank 1 intake manifold tuning valve control circuit. This will be an electronic problem so you will need to start a new question. Please post your new question here, you must be logged in.
