2004 hyundai Matrix reviews

Hyundai Matrix 2004

With respect to the engine vibration and the check-light and the mechanic not finding any problem, please note that the problem is caused by the jacks going into the coil pack. Apparently the engine heat deteriorates the plastic casing of the wire, what happens is it will get slack and the current will escape leading to signs of misfiring, which would make any normal mechanic change the plugs ,the plug wires, even the coil pack. Before going to these extremes, please ensure that the jack’s not slack, to aleviate the problem, simply switch off engine pull out jack, put back in securely, (dont jiggle it co’s if the problem exists it means the plastic is brittle and could crumble easily) and start car, then check. The light will blink a few times then stop, and remember once the prob starts the jacks on the harness will eventually need replacing.
