The car slowly continues to get worse... Tonight after work (sat for about 5 hours) it stalled on first start up, then took 2-3 tries of turning the engine over for it to fire at all. My stepfather is going to help me look at it later today sometime, I'll mention probing further into the throttle body to see if we can find and grime. Could a dying battery be the cause? I've noticed a couple piles of white residue where my battery is mounted on the top, and the battery itself looks pretty old. I'll update on here tomorrow if we make any progress.
