When do you need to replace spark plug wires?
The inner core can be a variety of types, from wire wound to spiral core, to anything in between. I know that older sets had a carbon core that gets brittle after many cycles of hot and cold and changing plugs can break that good contact, hence the need to replace the plug wires then.
What are the different types of spark plugs?
You can spend top dollar buying the more expensive iridium spark plugs, but if you reinstall your old worn out spark plug wires, you’ll never get the performance you expected. There are three types of spark plug wires; distributed resistance, inductance (MAG), and fixed resistor.
When to replace spark plug wires talk chaparral?
The plugs were something Shepard suggested and they nailed it never changed plugs on a 5.7 gm v8 inboard,is it a big hassel to get them out and new ones in ?, i can tell by inspection its gonna take the right setup on good tools. MERRY CHRISTMAS TO ALL
What causes a spark plug to go bad?
Vibration damage – Constant wear and tear caused by engine vibration can loosen the electrical connection at the spark plug. This causes an increase in the voltage required to fire the spark plug, which could damage the ignition coil as well as the spark plug wires. Heat damage – Engine heat can burn wire insulation and boots.

Why is my spark plug not working in my car?
It depends on what specific trouble code is being stored. If it’s a specific cylinder it could be the spark plug wire (if your car has them) or a bad fuel injector (if you have individual injectors for each cylinder). It could also be low compression in that cylinder. If it’s the generic P0300 misfire code, that opens up more possibilities.
What kind of spark plug wire does Merc use?
Merc is very proud of their wires based on the 500 deer price tag. I used the equivalent Volvo Penta wires for 104 deer. They were identical in length, coil end and plug end. The only discernible difference was the label inked on the wire.
What happens when you replace spark plugs and wires?
Thanks! When you replaced the spark plug wires, are you sure you got then in the right order? It is also possible that one or more of the new wires or spark plugs is defective. When you perform a maintenance function and the car runs worse after, you have to review the maintenance function first.
Why are new plugs and wires but still misfires?
I pulled it over and got it towed to my house and my code reader says a p0300…which is a random misfire code. So I figured i just need a tune up so I went and bought new plugs and wires and replaced the old ones. And to my surprise…still a noisy shakey rough erratic start and idle.
What to do if you change spark plugs and coil packs?
Then the next step is to do a compression test on all the cylinders to ensure they are holding compression evertime the pistons are moving the way they should and the piston rings aren’t in need of repair & check the timing to make sure it hasn’t jumped time , Certified Master Auto Technician for 25 years.
What to do if your spark plug is leaking?
If you find a cleaned washed spark plug, that is the one that has the leaking head gasket. If you find a wet or very dirty plug, that is the one tat is not firing. Diagnose the problem. If you find a washed spark plug. change the gasket and check the head and engine deck for flatness.
Most manufacturers recommend replacing your spark plug wires between 50,000 to 60,000 miles. It is also a good idea to replace your wires when you are replacing spark plugs, tuning up your car, or replacing other major ignition components such as the distributor or coil.
What are the symptoms of bad spark plug wires?
This is necessary due to the aging of the spark plug wires from exposure to extreme temperatures (hot and cold), engine chemicals (oil, grease, coolant, etc.) and electrical stresses. Common signs of failing spark plug wires include a decrease in power, acceleration, and fuel efficiency.
When do you need to replace ignition wires?
It is also a good idea to replace your wires when you are replacing spark plugs, tuning up your car, or replacing other major ignition components such as the distributor or coil. Of course, you will also want to replace your ignition wires if they are not working.
