It is possible the lower chain has jumped teeth...I am wondering one lats thought. The lower chain has two yellow marks...One for the idler gear & one for the crank....when I removed the upper timing cover and maid my marks on every thing...(before removing anything)...The exhaust & intake marks was not on the dark gray links on the upper chain...rather between links before the factory marks...Not really an issue..I placed it both ways and it still will do the same thing...Idles fine don't rev over 1100...I'm wondering...now...Is it possible I'm lining the crank gear mark to the dot on the idler baring? Would it even crank and idle? I have noticed...that the factory yellow mark on the lower chain is not lining up with the mark on the idler bearing...And yea...I could of just put the plug wire in the hole and it would of popped out to when looking for TDC..
