Been chasing my tail on this one.
Used car so I have no history on this car.
Car came to me with a concern of a slow rev and and would not accelerate.
Took it for a ride could not get the front a/f ratio sensor to go rich , pulled it into the shop put propane into the intake still wouldn't pull rich on the front sensor , the rear o2 was over 900mv , couple tests at the the front sensor and I called the front sensor ... Now I have a new ntk sensor in and it reads perfect but....
On the road test it now has great power gets up and goes like it should
Now when I hit about 5000 rpm in 3rd/4th gear it starts to studder and sets a p0244 code waste gate sol. A range / i have tried to find Boost data on 2 snap on scanners and one launch x431 diagun scanner and there is none , it has a Cobb aftermarket boost solinoid it is a 3 port set up Oem is a 2 port bleed set up , at idle car is pulling fuel -14% just looking for some input or direction . Waste gate sol. Dose function properly when I bench test it , map sensor seems normal current ramp on injectors and coils look normal
Thanks
