I got my '88 Ranger (manual tranny) a few months ago - it had been garaged for basically the previous 2 years. After fluid changes etc. it idled at about 1300-1500 rpm. Cleaned IAC valve, throttle body, linkages, lubed throttle cable etc. and it idled perfectly at ~850 rpm for well over a month. I started it up a couple of days ago and it threw the CEL on and died. Re-started, CEL went back off - after driving it around (ran perfectly) and getting it warmed up, the idle is about ~1300-1400 rpm and it's been that way ever since. Any ideas what to try?
The first thing that came to my mind was if the coolant temp sensor went out and the truck thinks it's not warmed up, wouldn't it also be running rich? It doesn't seem to be, but I haven't pulled the plugs to look at them.
