Good to hear its at least running better. For future reference platinum plugs, while they do last longer on average, are also normally less efficient than copper plugs. Kinda depends how much you drive the car, HOW you drive the car, and how often you like getting your hands dirty.

Well I went to the pump today and calculated mileage based on since when I changed the plugs Im now getting about 19MPG city and 25MPG Highway changing those spark plugs was a good idea because they hadn't been changed for almost 2 yrs since I first got my car as for the O2 sensors they are going to have to wait as I am broke because of a past speeding ticket I must pay in full now

Wow 2 yrs... good to see the jump in mpg. I get average of 22mpg per tank, mostly city, and a heavier foot than most.
