Terrible gas mileage

+1. Even with my cam and other mods, extremely heavy right foot I still manage about 17 city 25 highway (at 80)
Replace your plugs and wires, especially if you don't know the last time they were done.
Also, don't forget to check your blinker fluid and muffler bearings, I heard they can drop your mpgs.

I bought my car with 72k Miles. I was getting a mixed average of ~17-20 MPG... I had a manifold leak, my plugs and wires had never been changed, original battery, and what I'm assuming to be dirty injectors. within 3000 miles I replaced plugs, wires, battery, fuel filter, swapped to K&N drop in filter, LT headers to fix the leak. swapped to Mobil 1 full synthetic, used Zmax fuel and oil cleaner, seafoamed engine and topped it off with a 93 octane economy tune. On my automatic I was seeing over 30 mpg with mostly highway driving
