199 Lexus GS300. Failed an Emission test and the results were;
P0300: Random/Multiple Cylinder Misfire detected.
P0305: Cylinder 5 Misfire detected.

The car has been hesitating and misfiring on take off and/or any type of acceleration. Engine light, VSC off, and the ABS warning lights continue to stay on. It runs ok once I get up to speed, but as soon as I slow down and try to speed back up I feel the same all over again. Please someone help!

Try replacing the plugs. You have a misfire on cyl 5. Pull that plug and check it.
