I think my truck is making me payback big time for neglecting it so long. I deserve it.
I've been following your story somewhat, cmayna. I'm sorry to hear that this is happening to you. And, as a Metaphysicalist, I have to say that you could be correct in your assumption, as this is a Natural Law. Technically, it's termed "Combustible Engine Instant Karmic ComeUpIns".
The Solution is to invest more time in your truck, which I know you will. Then the Law of Grace Inna Garage will prevail.
Peace, Brother Bolter.
