It went to 1800 revs and immediately started back down. It did the same dead battery clicking When I jump started it the engine turned right over.

Does revving the engine help jump starting?

Your car's fluids include: Does it make this noise after every oil change or just after one in particular? I would like to hear other opinions on why the engine ran so eratically?
