Lately after driving my GTR for about 30mins it will start to loose a lot of power. The best way of describing it is that no boost comes on, however the guage is still reading positive boost. Also when it happens i use a lot more fuel up and theres alot of poping goin on from running to rich.
The car is still standard, running standard boost. I checked the ecu to see if i could get any error codes however it doesnt have any led's. how do i do this on an r33 gtr?
Im thinking the computer is running the car rich and retarded for some reason, maybe the afm's or coils. does anyone know what this could be
thanks for any help
