misfire under heavy load

[02TruBlueGt]

So car is acting funny and is misfiring under a heavy load only like when in 5th at very low rpms and when flooring through the gears, and all other times acts fine no problems. Changed out the fuel filter and all the plugs and 02 sensors and still acting stupid...


suggestions???
