Cars are so hard to read nowadays. One sound and symptom can be 6 different things

Got them replaced on my truck and the service engine soon is still on but noticed you said that hot engine temperature and maybe that could be cause the shop installed some electric fans but when I'm idling for more than 15 to 20 minutes the fans don't turn on, the engine starts overheat

Very well done. I'm about to change the knock sensors on my 2004 volvo xc70 because of these symptoms: rough idle with a pronounced dull thud and vibration that increases with RPM, poor acceleration (and I mean-really poor acceleration) a lack of power and a check engine light, although the codes were cleared because the battery was removed. I cleaned and tested the fuel injectors, performed a compression test on a hot engine and received good numbers across all 5 cylinders (165-170 psi), and installed new, correctly-gapped spark plugs. A vacuum guage connected directly to the intake manifold reads a steady 17"-18" (engine has 345, 000 kms/215, 000 miles) The ignition coils and boots were changed last year. I am more convinced than ever that the knock sensors may be the problem

I have a 1963 Chevrolet. No knock sensor, safety or pollution BS. Don't need Knock sensor. Why?
If it knocks I have two ears to hear.. Just let up on the pedal, which is located there under the right foot.
Wow it stopped How simple.

While somewhat informative, any benefit was destroyed by the useless captioning. Absolutely horrid. The CC actually is a detriment. Your video would be much better without it. People with hearing loss should watch all the other videos on knock sensors...
