hi my 1995 chevy s-10 pickup 4x4 V6 4.3L idles rough. It sounds like it is misfiring or the timing is off or something. It starts if I feather the gas and I have to keep on the gas otherwise it will stumble and die. I replaced the cap and rotor, spark plugs, wires, and vacuum hoses. I dont know what the problem is. maybe the oxygen sensor...idk. If you can help please send a message. thanks.
