I have a 1990 300 ZX none turbo. The car when running hot for about 40-50 minutes while ideling When give it steady gas it will shake and the idle dropped. Quicker gas and the car will run smoother. All Fuel injectors replaced, all coils replaced, all wires and spark plugs has been replaced. No mechanics seems to know the problems yet. Car has 95K timing belt not change yet.
