Well I finally got this CRV put back together and it seems to be doing ok... Turns out it was indeed a stretch timing chain, which was retarding the intake cam by and tooth. Installed a new chain, adjusted the valves and it sure smooth out the engine and drive much better... I still feel this uncertainty that it is not running at 100%... more like an 80%.. I am only getting 17mpg driving mix.. highway and city. and every once in a while i get this hesitation to speed up from a stop and of course no CEL..
