ranger rough idle/sputters/dies
i realize this was perhaps posted before but here we go again. I have a 2007 ranger 500 efi. It sat for a few years but has less than 60hrs on it. i fixed it up but has recently begun having issues. basically i start it up and starts idling high. it then beguns to sputter and eventually dies, sometimes backfires as well. i have a friend that is a gearhead and we have done the following: changed the oils and gas, checked the filters, took the carb apart and cleaned it along with the sensors... there might be a few more things but that just about covers it. at slightly above normal idle i can hear a small clicking sound coming from perhaps the bottom end but i have read that is normal. once i raise the throttle it all goes away; roughness, no miss from the bottom end... i have checked the sensor connectors and they are not burned. i have checked the wire harness and have not seen any opens or shorts. i wonder if something could have happened when taking the carb apart but it turns on and runs... any help would be great, thanks.
