Hi friends!
New to this group but in need of assistance because I'm super confused!
So my 2008 Vibe was running fine until a few days ago when I had to change my headlight and I disconnected the battery. I re-connected everything and the car started up fine but was idling heavy, which I expected because I've encountered the computer relearn issue before. I got to where I was going and spent a couple hours there. Left and the car started up fine. Went to a restaurant and after a couple more hours got in the car and it started fine. However, the next day when I went to leave, the car didn't start. The dash lights didn't turn on and the car didn't even try to turn over. I jumped the car and let it run a few minutes but once I shut it off it didn't start again. However this time if I turned the key to the on position, the dash did light up. I jumped it again and attempted to drive it to the store but it was idling super heavy and it stalled out at the first red light when I turned off the AC and the rpm went from around 750 to basically nothing. So I jumped it at the light and got it back home. I found some info online about how to get the car to re-learn the programming. I disconnected the negative battery terminal and cleaned off some minor corrosion that was on it and reconnected everything after about 20min and made sure it was on tight. I went through the steps of "reprogramming/teaching" the computer and it went from idling heavy to then idling as normal. I shut the car off twice and turned it back on with no issues. The next morning it cranked up just fine for me to go to work and I thought the issue was fixed. However, several hours later when leaving work it no longer wanted to start up. The dash lit up and it gave some minor power, but it didn't even crank when I turned the key, let alone begin to turn over. I jumped it again and got it home but now I am at a standstill of not knowing what to try next. The battery is only 2-3mo old. The car has 295k miles on it. Any help or suggestions would be super appreciated!!
