'91 R32 GT-R having some issues with cold starts. Wideband is reading full rich at idle.. the throttle stumbles when on it, or tries to stall when letting off. Idle is very rough and car shakes if I take the RPM above 2K.

Car's ECU is stock, IAT sensor was replaced a year ago. I know the mixture is supposed to richen up a bit for cold starts but obviously something is wrong here :p

I pulled the plugs and replaced them because they were fouled up and wet with gasoline.. however, the underlying issue causing it to be so rich is not addressed.

Any ideas?
