Scammer, the car is RHD, but you may be on to something regarding the wiriing system. Costee, we have not been able to test the IPDM as you suggested, we discovered the meter we're using is not giving the correct reading, so work has been at a stand still since we had to order a new on I will update you as soon as soon as we do.

The only cod showing up now is P0340, We did a comprehensive check of all the earth connections and they are all clean, however, we also discovered that there is a fluctuation in the current, it's running at 13 volts then it drops to 10.3 then back up to 13, then back down to 9.8, etc. Don't know if you could shed some light there.

Chassis Number is Stated V35-105207, that's the same number on the vehicle's frame

That's all there is on the plate, I realised that the car being manufactured in Japan, does not come with that 17 character VIN as you are accustomed to on the Infiniti models in North America

Hi Guys, I have a 2001 Nissan Skyline 250 GT(VQ25DD engine), for some time now I have been having a series of problems with it. The complaints started with the oxygen sensors and the car was giving off black smoke with a weird smell and of course a higher fuel consumption. Then it started loosing compression and jerking, I would have to turn it off and on a few times before it runs smooth.

I bought 2 brand new Genuine Nissan oxygen sensors, but still got the reading from the scanner saying the sensors were bad, along with the check light coming back on after the trouble was cleared. After tracing the electrical feed of the O2 sensors back to the ECU, we discovered that the ECU was sending no current to the sensors, also the car started to give a complaint that the crankshaft sensor was bad, again I got a Genuine Nissan replacement, then it said the right camshaft sensor is bad. I then got a Genuine Nissan replacement for that as well, it then said the left camshaft sensor is bad, again I got a Genuine Nissan replacement along with a new ECU and the car is still acting the same way, except that the O2 sensor complaint is now gone, but the compression issue with very little acceleration is still there ( the car cant rev above 1500 RPMs or it starts to jerk) , however when we remove the right camshaft sensor the engine runs a lot smoother at a very high rev and is gaining compression. I am at my wits end with this car, could you help? Really frustrated!

This is the list of parts changed thus far
Frame Number: BLGARHAV35DDA-A
Crankshaft Sensor: 23731AL605
L Camshaft Sensor: 23731AL622
R Camshaft Sensor: 23731AL616
Oxygen Sensor: 22690AL600
ECU: 23710AL500
