When my dad drove it:
The water pump blew on our way back home and it was towed into a Toyota Dealer who rebuilt the engine.
Then I got my license and now the van is mine:
Oil pressure sensor broke and lost all the oil. It was towed back into the shop for repair. Luckily, it was under warranty. Engine wasn't damaged, thank god.
My brother slipped on some ice on his way to school and took it into the ditch. Now there's a dent on the bottom side behind the right rear tire.
Air intake hose between the throttle body and filter box got a hole in it. Instead of paying around $60 for a new hose, we sealed it up with GOOP and taped it up with electrical tape.
Misfiring when warm. Things we replaced to try to solve it.:
Fuel filter. It ran a little better after that, but still kicked and bucked.
Replaced the rotor and the coil, this time, doing this ourselves. Runs a lot better, but now will run on 3 cylinders when it's warm enough. Since my distributor cap shocked me when I was adjusting the timing, this means I need new wires and a new cap.
New plug wires and cap.
New ignition module if plug wires and cap don't solve the problem.
New windshield washer tank and pump motor.
New stereo system.
