What gas mileage you have !!!!!???
I own 2000 sport using highest octane gas (its by manual) and my gas mileage horrible only getting 210miles per tank !!!!
what i can do or what need to be change to get batter gas mileage
I already done:
----year old oem spark plugs, injectors was handy cleaned (not cleaner in fuel tank)
----2,4,6 cylinder coil was replaced due to misfire
----fuel filter like 1,5 year old (it's should be less the 15k mile on it )
----both O2 sensors that before cat. were replaced due to check engine light
----seafome air system few times already since i got this car (curenly exhaust coming out fine)
----recently took car to mechanic (had some problem that were fix) he tasted fuel pump also and it was working fine
----currently i using 15w-40 oil due to weak oil pump (but that will use 10 -15 miles extra per full fuel tank)thats not big deal
----just replaced air filter (my old one was not even dirty but i replaced any way) thought it will help - but it didn't
what can be wrong or just not working right that can makes my car eat gas like that
OMG!!!!!! Why i have 12mpg !!!!!!! OMG!!!. help !!!
i was thinking maybe replace spark plugs to "Pulstar" and replace coil for 1,3,5 cylinder cuz i already replace for 2,4,6 like year ago, and on 1,3,5 is original 12 years old!!!!!
HELP !!!!! HELP !!!!
