Hey Guys, My brother has a 2000GT with about 100k miles. Shortly after he bought it(year or so), every other month he would have to clean water/antifreeze off the second sparkplug from the radiator on the right side if facing the car. Sluggish running was the indicator when this needed done. About 2months ago he and I replaced the Ford defective intake hoping that would solve the problem, it was leaking also. Well it did not fix it. Any ideas or suggestions as to what could be causing this?
