Sir, i have a problem with my hyundai accent. I see spark jumping from the ignition coil. And it is affecting my vehicles performance. sometimes it seems to be like the engine is going to stop. when i consult to a technician they told me to change the coil ignition and i changed it. It cost around 2294Rs. still the problem exists. What is wrong with my car. Thanks for your reply anoop

The problem could be caused be leaking High Tension cables from the ignition coils to the spark plugs.

• To confirm where the spark is shorting, take the vehicle to a shady or darkened area, open the bonnet and look to see the actual place.
• The problem could be at the joint between the coil and the spark plug high tension cable.
• It could be along the length of the leads.
• Alternatively it could be caused by a defective plug which is failing to fire correctly.
• If resistance has built up in any of these area's, or the spark plug cable is carbonized or cracked along its length it will short, taking the shortest distance to return from where it came: ie, the battery.Electricity will always take the line of least resistance.
• The best way of dealing with a problem with the leads or plugs is to replace them.
• While you're under the bonnet, make sure that the cable connecting the engine to the body is not broken and that the connection is intact and not oxidized.

If the coil is arching still after replacing it new then replace the spark plug wires. faulty wires will cause the arching and so will a cracked distributor cap replace it along with the wires and your problem will be solved
