Idling problem 4.0 ohv
I've got a 95 ranger with the 4.0 ohv motor. Lately it's been having trouble with idle. It almost never idles at the right level(650-850). It is usually always at 1-2k. While I'm neutral it with usually stick at 2k and then drop. Sometimes it will drop and the needle with shutter up and down between 1100 and 1300ish while moving. It's gettin old and killin fuel economy. I HAVE ALREADY REPLACED THE IAC VALVE. I recently had a new clutch and slave cylinder put (about 2 months ago) but it was doing this before that. I'm clueless and need some help guys, thanks!!
