Sup guys, I have a b20b motor in my ek. before this humming noise started, my water pump was messed up and I didn't know it. So my engine was always overheating, but I kept on driving it. Until after a while, when the engine idles real low, there's a humming noise. You can hear it come from the filter. When you rev the engine, the humming noise goes away, but once it gets low again, it hums. Can anyone tell me what might be wrong with it? Also, once in a while, i get a bog while i'm driving on the freeway. It feels like there's no gas going to the engine, but I have enough gas in the gas tank. The problem i'm having now is when i'm driving on the freeway, lets say i gas it for a while, like i'm racing, then wen i let go of the gas, the motor shuts off, is it the alternator? Any help would be great. Thanks in advance.
