Ok, i have a 99 grand am gt, the power steering on it has been fucking up, this is what happends. If i am driving under 10 mph or so, it is hard as hell to turn, like the power steering is out, or it also seems as if when i hit the breaks and try to turn it does the same thing, the only way i can get the power steering to come back into play is when i accelerate, or hit the gas in anyway. I have already checked the power steering fluid, its fine. Also, i had the power steering pump replaced about 4 months ago. Any ideas?
