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.

A vacuum leak like saturntech9 suggested would hurt gas mileage, also check the air in the tires, here is a guide on how to check for a vacuum leak.

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.
