Much of this is related to stalling problems I've had and tried to diagnose for years. That finally seems to be licked after replacing the fuel injectors and adding heat shielding to the coil and injectors (turns out the inline 6 has heat problems that can cause fuel leaving injector number 3 in particular to prematurely ignite).
Front axle replacement was due to a comedy of errors, which I'd rather not elaborate on because stupid.
I've only recently started tracking these expenses via software, so I'd have to go digging up paperwork to go back further than August.
Early August: replace front axle, roughly $1800.
