I am always around 100 miles when my gauge gets down to 1/4 tank of gas left. It does not matter if you are in it all the time or driving it turtle style. There is also no change between highway and city driving. When I first bought the car and got it on the road, it got about 115 to half a tank of gas all highway. But that is the only time. It used to get 13 mpg no matter what the driving style was but began to decline. It now gets 9-10 mpg. I measure by filling the tank, resetting the trip, drive it until there is 1/4 tank left, fill it, and divide the miles driven by how many gallons it took to fill. I even bought an SCT chip to see if getting some kind of tune would help. Mileage stayed the same, no matter the tune or driving style. The only code I get is 564.
I know this is not a good gas mileage car, but I have heard of people with more mods that get much better mileage than me. Also, the car has always smelled extremely rich but I have not been able to find a reason why.
List of new parts (Problem was here before all new parts):
Fuel Pump (190), Fuel Pressure Regulator, Fuel Filter, MSD Distributor, MSD Coil, and MSD Spark plug wires, Spark Plugs, Mass Air (76mm calibrated for injector size), Fuel Injectors (24lb), PCM (Used), ECT, IAT, TPS, IAC, and both O2's
List of car mods:
B-Cam, 1.72 RR, 3.55 gears, SCT Chip, x-pipe, and flowmasters.
Any suggestion or insight would be greatly appreciated.
