it misses and chugs under load. it used to do this only when it was cold for about 15 min; now it's all the time. no antifreeze is dripping on the floor but the level keeps going down. i'm thinking possible head gasket but wondering if it might be IMG since it used to get better as it warmed up. i'm basically wondering if ther is a "jeep thing" that this rings a bell for.
