Plugs are less than 3 months old and gapped to .054, same with the plug wires and fresh filters all around. I'm thinking maybe some clogged cats like someone suggested, good time for an O/R X huh. Added fuel injector cleaner 1 tank a ago. Going to clean the IAC tonight. I may replace the PCV also or I may not bother sense I will be doing an engine swap soon. I've only had the car since July so I've been going through it and replacing everything. Like I said though, I get 15mpg when I hammer on. As far as the distance on the highway about 3 minutes of town driving getting to the highway and about 7minutes on the highway and another 1-2 minutes in town getting to work from there. I use cruise off and on because its fairly flat. All the fuel mappings are the same as far as I know.
