Alright i own a 2.3L 94 ranger with about 170,000 miles on it. Lately it has been idleing rough. It only does this about 3 times in a day out of starting it maybe 7 times i will start it and it will be real rough then stall. I would then start it back up and play with the gas pedal, it normally idles about 500 and i have to get it at about 1,500-2,000 rpm's and hold it there for a second or two. I checked my oil it was about a quart low so i put a quart of oil in there. I recently put in a new air filter, i cleaned out the throttle body. I am clueless what it could be. After i let it idle high it idles normally and it runs great. My guess is maybe a new fuel filter, maybe i have bad gas. I am clueless help me out please
