It takes double platinum plugs you could also have a vacuum leak. The plugs get changed every 100,000 miles. How long since your last plug change?

I am not sure what type of plug I use but I think they was autolite plugs they costs like $2.99 per pug. But I am not getting the good gas mileage that I got in the pass will the spark plugs cause the gas mileage to drop?

For 2.99 a plug I doubt you got double platinum plugs. They can a lot of things effect gas mileage though. Remove a plug and see how they look and how they look.

No the number on the tires is maximum inflation newer cars on the drivers door or drivers door label there is a tire pressure label. Your car gets 30psi front and rear.
