I've got an '87 PU, 2wd, with 22re which idles very rough when particularly when cold but also when warm. I've changed wires, plugs, rotor, etc. as part of regular tune-up and while this helps a little, it still isn't particularly smooth. Seems to run fine at higer rpms. Would turning up the idle speed be a legitimate fix for this or should I be looking deeper for another problem?
Thanks for any insight.
