This lady does such a great job explaining repairs. She really ought to be the chief spokes(person) for your channel. Her honest approach to repairs is helpful. Very good camera work too. Thank you for this video.

Sea Foam in a fuel injector cleaner tool will clean most of the carbon out 9 out of 10 times, but BOY will it smoke for a little bit. Thanks for your knowledge.

Some people dont realize you can disconnect the CPS wire connector = crank shaft position sensor and wait 5 minutes and reconnect and some times the vehicle will start and have no issues

1984-1990 Cherokees don't store fault codes. Misleading headliner.

Only the 2000-2001 models have coil packs. I believe the bad coil packs causing a misfire is what causes the carbon build up.

I wish you were located in NYC! I am so tire of the faulty mechanics I have to deal with!

That crankshaft sensor and camshaft sensor will get you everytime. Thankfully, its a cheap easy fix.
Don't forget to leave your paper shim on the surface of the sensor.

Hello my name is Lorenzo Rossi, I manufacture testers for gasoline pumps. But I got a 2016 Toyota Tacoma pump, Part Number: 291200-1000. The strange thing is that it has 3 pins in its electrical connector. It is the first pump I see with 3 pins, they are usually 2. With your experience in Toyota vehicles, will you know why it uses 3 pins? I appreciate the information that you can give me. Thanks.
