patulong naman. I have a 94 honda esi. after driving then park for a while and leave, as soon as i turned my ignition on pumapalya na yung oto then as soon as i move the car a few meters ok na ulit....I've already replaced my distributor cap,the whole internals of my distributor, spark plugs, high tension, changed my oil and even the radiator.

plus i hear a humming sound in my engine and also if my engine temperature goes on the average level while driving you can hear that the engine idling goes up and down. please help.

thanx in advance
