Have a 2020 supercharged 165 that runs great on low to mid but hesitates or misfires most of the time when sled is at wot for more than a few seconds. Checked spark plugs, checked that the power valves are within spec, exhaust springs are tight, y pipe is tight, no leaks there. However, there appears to be oil residue on top of air box where it connects to the throttle bodies. The springs that hold the airbox tight to the throttle body assembly are all in tact and they are tight but can see oil/fuel residue sitting on top of the air box where it connects. Residue is evenly coated on each side of the air box. It seems that there is a little blow by occurring at the air boxlike it is separating from the throttle bodies when wot. Would appreciate any help if someone has had a similar issue thanks!
