More than likely it's your water pump, I had the same problem.
I found out what my problem was, it was my pipe-asm (elbow) hooks from the tensional pull to the intake, it was cracked and cause water to leak out... also my catalyst converter was clogged up, which caused my engine not to breath accordingly.
