im getting poopy fuel mileage
around 350km per tank on a jdm 1.5l d15b vtec running a p08 jdm ecu

ive replace fuel filter, plugs, oil, and oil filter
the distributor cap is good, never checked out the rotor on the new engine, the plug wires are okay

i run a cone filter, apc quality, nothing special all on 89 octane

somebody said get a new o2 sensor, and switch back to the stock airbox.

can other people speculate? ive heard i should get like 450 km per tank..

i also get that much on my 94 corolla
i have 16inch rims, exaust, intake, new platinum plugs, fuel filter, etc..

sometimes just a little over 300kms =/
im thinking its the big rims, exaust n intake..

check tire pressures and pull the spark plugs out and look at them they might need to be replaced. get your fuel delivery system (injectors) flushed and maybe check the gas tank for a possible small leak?? yes with a stock intake your mileage will improve no doubt however it shouldn't be that bad to being with... hows the temperature of the engine reading on your dash, personally I had shitty gas milage and thats cause the temperature sensor was busted and the ecu was dumping fuel in like made to raise the temperature up to normal operating temperature.

just some ideas tghere

i do need a new temp sensor.. ive replaced the thermo switch, thermostat, flush the rad, and i still run a little above middle.. and it never drops / goes higher.. how much in the temp sensor?

also, ive flushed the injectors last tank of gas. the plugs should be okay, they have less than 1,000 km on them (ngk honda oem), but ill check today anyways. im getting my falken azenis today to replaced my really f*cked up stock tires, so ill fill up today and see how it goes :P
