Question about 1990 Ford Taurus
My 1990 ford taurus 3.8L only starts when i press the gas down and if i let off it dies replaced the idle control valve thingy and battery what else could it be? it started doing it when i overheated it. also after i replaced the sensor and batter and started it black smoke came out of the back its been sitting for 4 months could that just be old gas or oil?
Try replacing the exhaust O2 sensor...

The starting problem could be head gasket if it got really hot..... black smoke wouldn't be oil, and gas would stink but not black smoke if it's old, it wouldn't really matter if it had been sitting for 4 months. black smoke is probably caused by a gas mixture problem, or maybe a stuck fuel injector.
