Cylinder #5 misfire Hey all, I joined not long ago & haven't really posted much yet. I've got a 2008 GP GXP back in August & just recently it started having loads of misfire in Cylinder #5. It only seems to do this around 40mph or higher, & not at idle. I've pulled that spark plug out and it looks just fine. What could be causing this misfire? Any thoughts, comments, suggestions?

REMOVE and clean your induction system
-MAF spray cleaner(MAF sensor cleaner or electronic component cleaner) and toothbrush, dont touch the actual sensor with anything but the spray
-TB remove and clean using throttlebody cleaner, apply a thin layer of vasaline or die-electric grease to seal proir to re assembly
be sure to reassemble all connections tight and you can apply a little of the vasaline inside any of the vacum lines( look in them you will see an oring in there, lubricate it)
Should take less than an hour
