Question about 1990 Nissan 300ZX
Sounds like you have a problem with the coolant temp sensor, could be sensor or wiring. The coolant temp sensor tells the computer how warm the engine is so that it know how to adjust the mixture, a cooler engine needs more fuel. If the sensor or wiring is messed up, the computer gets a signal that the engine is very cold and the computer gives full rich to the injectors.
