I have a huge oil puddle from underneath the car, its right where the transmission and the engine meet. When I turn the car on, its starts, then it immediately dies...it will not idle. The only way for me to keep it alive after starting is to hold the gas and keep it about 2000RPM. After the engine warms up a little bit, white smoke starts coming out from underneath the car, in the approx. place where the oil is leaking out of, and it stinks of what smells like oil and tranny fluid...maybe more tranny fluid than oil. I hooked my computer reader to my car and it says that all 4 of my cylinders are misfireing and that my knock sensor is malfunctioning, I am currently replaceing my knock sensor, and I am in the process in getting both my head gaskets replaced(i havent purchased them yet, i will soon though)....besides these two remedies, does anyone have any suggestions?
