It's been a long road but I've got all the right bits put on my JDM motor; exhaust manifold, EGR valve, solenoid and constant vacuum valve, P07 computer, used 5 wire O2 sensor, but I kept getting a code 48 (LAF sensor) engine light, so I bought a brand new, 5 wire, wide band sensor, disconnected the battery to reset the computer and it STILL came back. The engine light was on for 8 months when I had the P07 computer hooked up with the CX 4 wire O2 sensor, before I got the wiring together.
I do seem to be getting better mileage but my speedo jumps and doesn't work sometimes and doesn't record mileage when that's happening. Could it be a dash problem?
