Okay so my maintenance light on my 95 Accord EX Has Turned red from an orange. I've changed the oil and air filter when it was orange and now it's red, which i think is worst. And one technician said that i needed a new "Plug Gasket" L.P.T.S. I'm still wondering what it is. And by the way i'm not a car person so i need a little help if possible.
