Tuning Help When I first got the car it was getting 25MPG all stock, then I took it a site sponsor to get the car tuned, then the gas millaged dropped to about 24MPG. Then I gutted the cats, added an K&N air filter, and SLP lid, and did a datalog on it and was average about -3 Long Term Fuel Trim. After putting an additional 10K on the car, and with no additional changes, gas millage continued to decline to 22MPG, and the data log indicates 7% lean one time and then 14% lean. So I changed the o2 sensor(bank2 sensor 1) and the car still runs 14% lean, when I pulled the sparkplugs the plugs look to be running slightly rich. Anyone have a clue why the gas millage is going down, yet the computer is saying its running lean, but the sparkplugs look like its running rich? I do have LS1Edit, but don't know were to start.
I do not get any gas milage (10-12 only with a4/stall)but I use
