Plugs have about half the life on them as I did have them changed about 70-80kmiles after feedback from a auto crossing colleague stating they looked brand new when he did his at 60k per the interval. I'm currently running 105k miles on chassis. But I also think my problem finally showed itself this morning.
My battery was flat out dead this morning. It's a redtop optima and it just turned 8 years old last month. I jumped the car with my charger to get to work this morning. It recharged enough on the drive in to restart as I checked it after I backed in on enough of a slope I could push and pop the clutch old school like if needed.
Found the same Optima battery quickly at O'Reilly's a few minutes from work and swapped it this morning in their lot. Borrowed some 10mm wrenches from work. Nice to be in a role where I have tools to use in a pinch.
Still wasn't 100% convinced this was my smoking gun, but at it's age, battery was an easy swap and made sense as I've seen low batteries cause problems before they flat out fall on their face. Voltmeter sure would be nice in these cars.
Still not 100% sure, but I took the time to run up and down the freeway and pull into my 7k range where my CEL would consistently flash with old battery and generate the P0301 code. No CEL light observed and I was well into the range it threw codes before the battery change. I need more drive time before I'm fully convinced this was the issue, but these results are better than that of changing the coil, so progress nonetheless.
