Quick advice before I have time to search through the history of 'MUD. Hopped in the 100 to go to work today and the UltraGauge beeped with a notice of a pending P0300 code as I pulled out of the driveway. I parked it and took the 40 to work, but I'm curious about next steps before throwing money at it. 2007 with ~150K miles. Been running great with no real issues other than a gas cap code when it was really hot last week, and excessive battery drain with the fridge running lately.
Should I drive it a couple more drive cycles to see if the pending code actually turns into a P030X specific cylinder misfire to help diagnose it, or just avoid driving it at all and try to figure it out from the P0300 code and the many, many things it could be? My initial search seems to suggest a bad coil, or maybe injectors, but it's been running fine with no hint of either, including the brief run this morning. The only weird thing I'm thinking of now that I type this has been two times after a dead battery in the last couple weeks that the first start after the battery charge, the truck didn't start with the normal turn of the key. Started up fine both times on the second attempt, and ran a tiny bit rough for maybe 5-10 seconds, but then it was fine.
Thanks in advance. I'll search more later, I promise.
