R32 Gtr Misfiring Spluttering And Chewing Fuel

[Midnight_Blue_32]

Hello All, Ive seem to have myself a bit of drama with my 32. The engine is freshly built, but pretty much standard apart from splitfire coils, pods and an exhaust. I've probably done about 400km driving since building the engine and it was running fine but now it seems that the car is running very rich, blowing black smoke and kinda hestitating while just cruising but really lacking the power when I get on boost. Since this problem has arose I've checked all the cooler pipe and cleaned the plugs because they were fould up and I'll be swapping the coils over today to see how that goes. Has anyone had a similar problem so I can try to isolate the problem. Any help would be great.

Cheers

Check the (ECU's) coolant temperature sensor to make sure it's still telling the truth to the ECU. It's possible that one or both oxy sensors shat themselves. This is especially possibly if you used a non oxy sensor safe silicone to do any gaskets when you put the motor back in.

Also if using a standard ecu, bridge the wires and see if it shows up any codes. I had a similar issue and turned out to be the AFM playing up. Pretty common for 32's and been that you've just done some work on it may have been hit or so during the work. All it takes is one dodgy wire lol

It's all sorted guys. Turned out to be the twin turbo pipe gasket. But I checked the codes aswell and turns out my afms were stuffed so I've fixed those and it's running sweet
