What is the significance of changing spark plugs?

[eureku]

the wires seems to not hold on tight to the spark plugs no more.
How many K miles that we need to change? how much for the parts V4-hondda accord-89?

I don't know what U mean by saying this "the wires seems to not hold on tight to the spark plugs no more."
For '89 Accord, there are 2 engine types (DX, LX has Carb, or LXi has EFI)
I recommend changing the plugs every 15K miles (help on gas mileage)
Use Nippondenso plugs (price from $1-$1.50 each)
It takes about 10 min to change 4 of them.

COldwind, how many Kmiles that I need to change the rubber
cord connected to the plugs also? one of them does not keep in contact well with a plug.
my car is SEi

Question: How many miles a spark plug wire can last?

--> It depends. The rule of thumb is its resistance of the wire from one end to other end must be less than 15K ohm. Use an ohm meter to measure it.

Check its insulator for crack or worn. If there is, then replace the wire. Humidity can cause spark and misfire and even hurt yourself if you touch it. A worn wire can reduce your car's performance greatly.

While you are checking the wires, don't forget to check your distributor cap for any crack or worn. Most of the time, when you change a set of spark plug wires, your car's distributor's cap likely needs to be replaced, too.

Question: one of them does not keep in contact well with a plug.

--> Have you tried to snap the end of the wire properly to its plug? If its metal at its end is wide open for the plug, use a pair of needle pliers to make the holding smaller, and try again. Otherwise, it seems the wire gone bad. I would suggest to replace that wire.

One more thing, I would recommend to replace all the wire with the same brand.

Good luck and let me know how it turns out.

LXi (Fuel Injection) is a good model for that year

Tuanduc has the answer for U

Personally, I recommend people change the plugs every 15K mi and the wires+cap+rotor+PCV valve+air filter every 30K mi. This is just for good maintenance.
Some plugs can last 60K mi easily but the plugs are cheap and new plugs help your engine start fast, run better, and give better gas mileage

For ex, some manufacture recommends oil change every 5K, some 7.5K ... but I change it every 3K/3mo. Your pick!!!

alot of things I learned in this forum, I love to learn more about car stuff....thanks all, special thanks to Coldwind He's helped other member alot....and it's made me learned alot too...cool forum....thanks all

spark plugs are actually below the four holes that line horizontaly along the valve cover....

and 94-97 accords <5th gen> are basically the same..
slightly different in parts...<v6 engines are obviously different from i4>

more specific about your car???.


If you have the camry 96 V6XLE, you better not to change the spark plug on your own. There are 3 spark plug in front and other 3 are in the back. It the pain in the a$$ to change those plug. << Some mechanic don't change them for you becuase they are lazy >>>

If you have camry 97 is more easy than the older model...
