Having a hell of a time finding a misfire issue!

Problem started last week, in OD when applying a little throttle to gain speed it sputter's/hesitates! Every once and a while it will miss here and there but mainly with the most load is when it act's up the worst!

I've tried different set of coilpacks/wires/plugs and cleaned the MAF! Fuel pressure is good according to the gauge on the pillar, replaced 02 sensor's as well and still no improvement!

Car isn't throwing any code's at all, kinda stumped! Any advice would be greatly appreciated!

 

Have you tried doing compression and leak down tests?

 

No, didn't see a need to but I guess it wouldn't hurt at this point!

I also pulled valve covers and checked for broken valve springs, everything looked good!
