Recently my vehicle has lost power and a strange pinging and knocking noise. I replaced spark plugs & wires, cap & rotor, traced some wiring and everything seems to be ok except that NOISE.
Hi the pinging you here is ignition firing before it should but if you have a knocking noise i would suspect the worse but try doing a compression test first see if everything is in order then if this seems ok have you put fuel in it just before it started if so change your fuel if not see if the electrical system has a knock sensor if so run the engine and tap the block close to it see if engine revs drop if not replace but the knock is a piston best of luck yates210456
