Hey everyone I have a 1988 Jeep Comanche with a rough idle after I drive it for a bit. cold starts and driving it does fine but when I drive it to work by the time I get there the oil light is flashing and it sounds like its missing. I replaced the idle air control valve already and the previous owner did a head gasket. If anyone has an idea as to what could be the culprit that would be awesome.
