So, I bought an fj60, when we bought it it wouldn't idle at all. after some research I found that this was related to a vacuum issue in the airpump. after resolving that it ran great(in ayard and on a short drive, however after about 1hr of wheelin, the issue came back, and had an added symptom. I now am losing charge. So my question is, would an issue with charge and alternator cause an issue with idle? I imagine that it could but just looking for some confirmation that I should pursue that
