I noticed when I was sitting at a stop light, that my oil gauge was idling. Before, it was sitting at around 60 I guess that's just a little past half the gauge? I'm not too sure.
While my Tahoe was sitting, it would just idle. It would move a little farther and then some back. I watched my truck do this for a minute and a half while I was sitting there. Once I gave the Tahoe gas to turn, it immediately went back to where it was (60)
I got to another light about 2 miles down the road, it did the same thing. Idled. Then once I gave it gas, it went right back up. This was on a Friday night. I parked my truck and didn't move it. Saturday evening, I went to turn on my truck and it wouldn't start. It sounds like it wants to but wont. I'm not sure what to do. I tested the battery. Works fine. Even put a different battery. Still didn't work.
