The 1997 limited (shitbox) sat for a few months and when I fired it up. It seemed to develop a misfire. So I plug in my bluetooth telling me cylinder 6 was the problem.. So I quickly swapped 2 coils... Still had an issue with cylinder 6. No biggie quick compression check. All was good. So most people would have verified the plug wire and the spark plug. Which is a very good thing to do. They both have 25K on them so I just moved on past them. With good compression, coil leaves us with fuel. I removed the upper intake plenum and went after injector 6. I already had one injector fail on the other side. I replaced all the injector seals on that side when I replaced that one injector. I did the other rail now and just replaced the one injector. The rest got all new seals while the fuel rail was off.. Anyways, Replaced the one put it all back together and the Misfire is gone.

Oh the Shitbox injector project.....After a week of it being Fixed... It developed a gas leak...I tore that upper intake off 4 times to fix it.. I figured it was something I moved or messed with when doing the injector changed. I even went as far as replacing the return and supply line as it was leaking on the back of the engine. Finally after the 3rd tear down I spotted it... I had the 6th injector o- ring pinch when I originally fixed it. So after a week it tore and was leaking. The injector didn't seem wet or anything the first few times I took it apart. Its impposible to see in there even with an inspection camera. However, after the 2nd tear down. I even powered up the fuel pump to see if see it leak everything was not leaking. That's when i put the new supply and return line in. So after putting it all back together and firing it up watching the gas flow again.. I tore it apart very quickly, ( I wouldn't know why i got so fast at doing it.) I finally saw a wet injector and knew exactly want happened. I add a photos later.

Still daily-driving the winter 5-speed. I was cruising along and thought, *man, that engine whine is getting way worse.* After about a two-hour drive, I figured I’d better investigate.
Pulled all the auxiliary belts off and—quiet as a church mouse. Huge relief knowing it wasn’t the timing belt or anything major. That pointed to a bearing issue somewhere in the accessory drive.
Started checking everything over and found the culprit: the power steering pump had a ton of play, especially in the front shaft bearing. Dug into the parts inventory and, luckily, had two pumps in stock.
Swapped it out, put everything back together, and took it for a rip—problem solved. Now I just need to snug the belts up a bit since they’re not quite tight enough. Nothing like a random belt squeal paired with watching your voltage drop. The power steering belt needs a little more tension too.
That’s tomorrow morning’s job.

I rebuilt my first 3rd Gen 4 Runner starter. Just the contacts and plunger the stater contacts were really good yet. I also re-brushed a sienna denso alternator. I would make sure you have good clean JIS bits and screwdriver bits As I had to get new screws in the denso due to a slightly warn screwdrivers.
