We need to run the codes because it sounds like you may have a clogged catalytic converter. you can get a code scanner from Amazon for about $20.00.

Here is a guide/video to show you how:

If no codes are present, I would try replacing the turbine shaft speed sensor. here is how the job is done in the images below.
