High gas mileage usage!!! Help!!!
I own 2000 Sport, using highest octane gas and my gas mileage horrible only getting 210 miles per tank or 14mpg !!!!

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
----using Castrol GTX 10w-30 oil since got this car
----just replaced air filter (my old one was not even dirty but i replaced any way) thought it will help - but it didn't
No check engine light !!!! Car running great!!!
