Spark Plugs Question

CBuch24 · 03-03-2006, 05:59 PM

Lately i have noticed my gas mileage going to the $hits. I was thinking it might be the fuel filter or the spark plugs. Does anybody know when your supposed to change them?

Thanks

Stock platinum plugs are good for 100k miles. I would change them at 50 though.

Not to steal the thread, but I was planning on replacing my plugs before 30,000mi. I bought the car used in October with 25,000mi on it, and the only thing i had done was an oil change. So far i have only put 2,000mi on the car. In like 2 months i was planning on changing the fuel filter, spark plugs (NGK), and doing a radiator flush. Should i leave the plugs and just do the radiator flush and fuel filter?

Plugs are still good but doesnt jurt to change them, you can do the radiator flush, and you change the fuel filter if it hasnt been done before.

How many miles are on the car might also check into your air intake filter as well

I wouldn't even worry about the plugs at this point unless the car starts running rough at idle or something of that nature, even then there are a blue million things that could cause a rough running car. Radiator flush, fuel filter and air filter are excellent ideas though.

I changed mine at about 80k and the car seemed to run a little smoother. Go pick up some Seafoam and a new fuel filter and see if that helps anything. Also, your o2 sensors could be taking a crap on you.

Is seafoam a cleaner? How do you use it and for what?

yea it is supposed to clean out carbon deposites and a whole bunch of other stuff. I used it on my old car and it was a definate good change. idled smoother and ran just plain flat better.

Leave your plugs alone, stockers are good for 50k, its a good idea to change the fuel filter but not really needed since you don't have that many miles on the car. Do it at around 35 or 40.
