Wife texted me this morning that our ‘06 had trouble starting, ran like crap, and threw a CEL, so she parked it and took another car.
When I got home and checked it out, the Scangauge said the battery was 11.5V and CEL was P0301, which is cylinder 1 misfire. I put a charger on it for a couple hours, cleared the code, and after starting it and letting it idle a bit, took it for a 10 mile drive with a mix of stop and go and then some freeway at 70mph. It drove flawlessly and ran great during that test drive.
It’s got 125k miles, plugs were changed about 15k miles ago, and I don’t recall ever getting this code before.
We have not been driving it much lately, and the AGM battery is now nearly eight years old. I have been waiting for Costco to get 24F AGMs back in stock for what seems like forever… I know the battery is older but when it’s charged back up it keeps going.
Back to my question: Is the low voltage when she tried to drive it today the most likely culprit for the P0301? Anything else to look for… other than perhaps a new battery?
