Cylinder #3 is the middle one on the passenger side of the engine. My bet would be a bad ignition coil. Higher engine rpm's generally have a stronger spark than lower engine rpm's.
EDIT: Late to the party. I didn't see there was a 2nd page for this thread lol I'm glad you got it figured out!

Yeah we are all good now, I've got three denso coil packs coming in today. Nipping this problem in the bud for another 20 years hopefully haha.
Probably going to order a spare injector just in case as well....
