Are you guys serious 30 mpg? I have a 2k ssei and average like 20.4 according to the computer. Also the engine at idle once its warm is some what roughi it doesn't seem to miss it jhust seems to lope a little is this normal or is this a bad sign?
It depends on my hightway/city ration, but if I do close to a 50/50 mix, I get around 21-22. That'* with new wires, plugs, O2 sensor, 1 new coil pack (rusted terminal), new fuel filter, new air filter, and cleaned throttle body.
