where to begin - what an awesome video - changed my knock sensors - return of my effortless smooth 6.0L Yukon...... what a difference - transformational. The video really enabled this to happen. Based on my research I used OEM replacement sensors and harness, with high quality generic gaskets. Also spring for a gasket for the throttle body. Access to the intake manifold bolts was not easy and the clips for the fuel injectors were also a PIA job - but with patience, knuckle joints and extensions, all manageable. Job took me about 5 hours total.

One of the smoothest videos ever, loved how straightforward to the problem he went helped me out so much thank you.

This guy is awesome and very professional watching this video was the key to my success on working on my truck. Thank you. You rock my boy.

Absolutely amazing video. It's nice that these GMCs are easy to work with in the first place, but this guy makes it even easier by clearly going through everything step-by-step to the point that even a rookie like myself can get it done. A couple of things I learned along the way though, just due to my inexperience: 1) Avoid using brake cleaner on the plastic intake manifold, as brake cleaner may damage plastic, 2) The fuel line may be rusted and hard to get loose (also, I apparently had two fuel lines on mine), 3) The fuel injectors are the ones closer to the intake manifold

Absolutely one of the best how-to videos I have ever watched!!! Really outstanding!!

yup got to take it to a mechanic for this. 💯this is too much for me 😭

Great tutorial. You are defiantly a professional.

Hi I have 2003 yukon xl 2500 6.0L. I encountered some problems and fixed them, but I have a problem for which I do not know the solution p0327, p0332, p0135, p0300. I changed the first and second knock sensors with the wiring harness, but 02 sensor I haven't changed it yet, and I cleared the codes, and with a test drive on RPM 2500 to 3000 (check engine) and after checking it showed p0327 p0332 p0135 p0300

Thank you so much

It's called an intake plenum

Can the knock sensor cause engine to starve for power and not allow the transmission to shift

Mine is knocking after doing this what happened

Can i ask which size of torque wrench do you used?

Yikes!
