My problem is when i drive the car as soon as it hits boost at 4000 rpm the car will fall on its face. The car is a 82 turbo motor with the z31 maf and ecu in it.
I know this problem has been discussed before and i have done countless searches and cant find an answer that works.
heres what i have done so far, I have cleaned all the connections with brake clean, i have checked the fuel pressure when i am driving and it doesn't loose pressure at all, i have bought a wide band o2 sensor and is telling me that my car is running lean on boost.
NOW heres the interesting part, i diconnected my CHTS and the car ran fine an still went lean when i was driving it... like 20:1 AFR!!! I have also replaced the maf?
Now i am wondering if there is something i am missing? what would cause the car to run lean all the time? the car is a 240z so it does'nt have a speed sensor, would this cause a problem like this?
