Charged the battery and started the car after not driving it for about a month and a half and the check engine light was on was illuminated for the first time ever. Figured it was because the battery was dead (AntiGravity lithium) and maybe the car lost some parameters so drove it around for about an hour and even power cycled a few times but it didn't turn off. Hooked it up and it read:

P068A $07E8 Generic

ECM/PCM Power Relay
De-Energized
Performance Too Early

Any ideas where I should start looking first? Any help would be greatly appreciated

Try clearing it and see if it comes back. Probably something to do with the lithium battery
That’s what I was thinking! I’ve had the battery for more than a year now and haven’t had problems with it but have heard of others that have. Hope that isn’t the case that it messed something up.

I’ll try your advice and try to clear it then drive it again.

Tried it. Didn’t work unfortunately. Light came back on right away.
