Hi I have a gtr 32 completely stock and lately I have been having this problem which no1 can work out.

The car will not boost over 10psi and when you drive it between 2 and 3 revs the car will make this strange noise from the blow off valves. Like it keeps coughing. Also on the ecu it comes up with error code 34 faulty knock sensor.

But I have been told it can not be a faulty knock sensors because the car can run without them.

Also the car keeps over fuelling it gets about 100-200k a full tank.

There is no vucuum leaks.

Any ideas would be good thanks.
