Hello and welcome to JustAnswer! I apologize for the extended wait time you experienced, I've only just come online now and would like to assist you with your question.

There are many possible causes for a lack of engine power and it will require some testing to determine what is wrong. The problem could be a fuel delivery issue, a sensor problem, injectors, wiring, the turbo itself, or a boost leak. The first step in diagnosing the problem will be to use a scan tool to see what fault codes have set and go from there. IF no related codes are set then some data will need to be monitored while driving to know what direction to go for testing.

My goal is to give you the best experience possible! I hope I have earned a 5 star rating! Please remember to rate my service by selecting the 5 stars at the top of the screen before you leave today. If you need more assistance, please use the reply box and let me know.
