1998 Hyundai Elantra Question: check engine light
Electricity wants to take the easiest path to ground. Moisture certainly provides a convenient path to ground for spark. Porous spark plug wires certainly fail in wet weather. Ensure the spark plug wires are routed and separated as Hyundai call for. Hyundia techs strongly recommend NGK spark plugs part number 6953, An intake manifold gasket can cause a misfire in one cylinder. I was trying to find an article I read about an engine wiring harness problem some Hyundai have. Hyundia are very good at offering all there bulletins and service manuals on line for free check there link below www.hmaservice.com - patrick mannion
