2018 accord 1.5 MT with 135,000+ miles.
I stop driving it for about 2 weeks. I was doing some suspension work on it and the battery did die. The car was driving ok till after a few miles. All the lights and check engine lights came on. I noticed I had no boost at all. Having an AEM boost gauge I saw I had no boost. It said to take in to the dealership ASAP. So I pulled over and unplugged the battery for a few seconds the car was back to normal.
The following morning I when out for an alignment. Everything was ok till after the alignment was done. All lights came back on. So I took it to my homie's shop. To reset the computer and see if any codes come up. Everything came up lol but he did a reset on my ECU, car worked great for a few days. He said I may need a battery but we need to run more tests on it.
A few days later the same thing happened, So I did the same and unplugged the battery, car runs great till I turn it off. Once I turn it on again no lights go on. If I gas it to like 4.5 rpm all lights go on. If I unplug the battery and turn on the car all lights go off till I turn off the car n turn it on again.
Has anyone run into something like this? Help!! Do I actually need a battery?
