Went to the parts store and the battery is only reading 11.8. They think bad alternator too. I'll work on getting it out again and replacing again. Thanks for your help.

Update: I wiggled and pushed together every sensor and connection I could see/reach, including side clip if alternator. This helped. I'm able to now drive as usual but the dash lights are still flickering from time to time. It's not the Alternator (brand new). I'm going to take my car in to parts store and ask them to load test my battery and help me find the map sensor (internet says that could be a culprit?).

My battery wasn't charging so I replaced the Alternator. But now the engine idles well at first but after a bit gets rough and when in Drive, it won't get above 2000 RPM. No engine codes. No check engine light. I've tried unhooking the battery, waiting a couple hours and then negative first - then positive to see if that would help. No luck there. Any ideas?
