Having misfires a few times under full boost recently. Does not happen all the time. When just daily driving there is no sputtering/poping or rough idling. Starts up just fine in the AM.Mainly occurs in 4th gear… IDEAS?

had VERY similar problems in the SER, only under WOT, drover perfect every other time, turns out it was 2 faulty coilpacks. so yeah, i’d bet its something fishy in your plugs or wires or GSR distribee or something
My guess is that the hydro-pin on the splinter-coil is starting give. I would replace the entire splinter-coil with a new oxo-tube with variable tube drive technology.
And just to back that up I would say grab a emissions controlled aqua-spring as they are known to make a more efficient path for the VTDT with the oxo-tube.
