[Unseenspirit2002]

I have owned this 2002 TE PT Cruiser since February. When I bought it, it had only 24,996 miles on it. A rare gem, truly, however, it now has 27,148 miles as of this morning, yet I get really crappy gas mileage and I mean real crappy. I've owned big block chevy's from the 70's that got better gas mileage then this thing does. We're talking 175 miles to a tank and that's if I'm playing Grandma, but usually we're looking at 155 miles to the tank spread out between city and highway, with more driving in the city then highway. With gas in Denver going for $3.73 for Regular....well that just plain out right blows! It runs fair enough but the idle has gotten rather rough over the last month or so. What's the best things I can do to get better gas mileage? I mean for Christmas sake it's a four cylinder it's supposed to economical not some high-end luxury item!!! I'm thinking new plugs, wires, and a K&N FIPK, but what's the best plugs to get and what's the best wires to get? Thanks!!!
