So it's been a few weeks since I posted the last thread now and the G40 is still not sorted or running properly. Since then the chargers been rethreaded and all oil leaks have been sorted.
I'm thinking it may have gone into some sort of back up mode as when disconnecting any sensors, the engine still seems to run as normal, almost misfiring and blowing black smoke pretty bad.
I've changed the plugs and let it run but no difference what so ever, all the plugs fire accordingly but when taking them out on inspection again, they all seem to keep getting covered in soot. I done a compression test while the plugs were out and all seems good.
The coolant light inside seems to be constant on even though it's to the max in the tank.
I drove the car last night 50 yards or so until boost came through, when it did come through, the car seemed to panic and began kangooring then when letting off the throttle seems to cut out.
I've tried explaining as much as I can although it may seem a bit jumbled but I need some help here people, I'm at the end of my tether as to what it can be.
