    RE: 2004 LS430 with 91K

    I thought I would reach out to you for troubleshooting assistance with a P0303 code which accompanied the Engine & VSC Check lights, I haven't attempted to reset the codes, since I believe I have a real issue, i.e. the car is running rough. I affirmed Cylinder 3 is misfiring as there is no change in the idle when opening the coil connection. Additionally, the spark plug/coil & wiring appear functional as I am getting a spark at the coil. Spark generated in Cylinder 3 looks very much like Cylinder 5 spark. This coincides with operating Cylinder 3 coil in Cylinder 5, & vica versa (C5 coil in C3 does not restore idle). Nevertheless, put in a new spark plug into Cylinder 3. Seems like something fuel related is contributing to the C3 misfire. I am hesitant to use fuel injector cleaner or attempt additional troubleshooting without some guidance or input. Appreciate your thoughts. TIA
