re: #106 EPR-radar
This kind of on-again, off-again problem does not sound like a seized engine to me, although I’m no car expert.
My parents had a very similar problem in one of their cars which was eventually and with great difficulty traced to a little cardboard disk from a container of dry gas that had gotten into the car’s gas tank and would occasionally cut off gas flow to the engine as it moved around.
Since yesterday, it hasn’t started. When you turn the key, it sounds like it’s grunting to start, but that lasts like a quarter of a second.
