I'm getting the same trouble codes and same response on my car, P0131,P0171,P0103 and P0140 I am in the process of swapping out all vacuum lines, cleaned the MAF and my wastegate is less than a year old. Let me know if you figure out the problem with yours

i kno what they are im just saying cuz there all replace buht car is still being floored and it wont go all it does is suck up are and it ecelarate lil by lil

it is you a/f ratios that are making it run like s***, but, you have to figure out whats causeing the bad a/f ratio. From the sounds of things I would put my money on a vacuum leak considering you have already changed out both sensors. These cars are notorious for having crappy vacuum hoses and tons of leaks. I'm in the process of changing all mine over to a silicone hose kit i bought from *************.com only about a quarter of the way through the project

But wuht if I change the vacum what if it still goes those that mean I have to tune the car cause the air ratio is off

 

[tmadmsp]

I dont understand what your trying to say. basically you have to figure out whats causeing your check engine light. once that is fixed your car should run fine without tuning it. try unplugging your negative battery terminal for at least 30 min to let all the trouble codes clear. hook it back up and take it for a spin you should notice the power is restored to your car.
