Firstly, thank you so much for all the help you've provided already! I first had a TCM issue. Had that replaced and programmed. Then, I had an O2 sensor issue. Replaced it with a Bosch sensor, still had a CEL on, realized Bosch's heat resistance isn't correct for my car, so now I've bought the AC Delco for my car and will have it put in after the part comes in. Now, I'm getting a slight movement in the temp gauge. I'm pretty sure it never used to go over the mid-line at all. Now, it's going just above it but not quite to the next line. It's not near the red yet but I don't want to wait until that happens to do something about it. It'll go up just a little, then go back down to half. Does this sound normal? Or does it sound like there may be air in the coolant system? I just had a new serpentine belt put on too. I'm going to have that checked when the O2 sensor is put in to make sure it's on right.
