Good video sir Reminded me of My dad's style Of checking Engines when I was A kid in the 1980s He would triple check always Again sir good work! God bless..

One additional diagnostic test would be cylinder leakage. This is done by charging the cylinder with air and checking where air leaks out...intake valve, exhaust, through crankcase, or into coolant(radiator cap removed). It gives more information before removing the cylinder head. There are devices made for this purpose, they measure per cent cylinder leakage.

Ralf, I just had a 2013 Equinox with the #2 cylinder misfire. Did the coil swap and then compression check and sure enough #2 had no compression. Pulled the head and found one of the exhaust valves in #2 had a piece chipped off. Don't quite know how that could have happened but I decided to replace all the valves. Nice job on the diagnosis.

Thanks I will have to check mine, I'm getting a misfire, reduced engine power. Rough idle has I drove it home. 10 equinox 2.4l 4cyl Great video

This is more of a schooling video on what todo it's long but gives a point of view it's pretty good

I am picking up a 2015 equinox for $500, has a undiagnosed engine problem but from what I am told it has a different problem that what you just diagnosed. I watched your video and you did the same exact thing I would have done. Just hope this car I am picking up is not in the same condition. I really appreciate the video.

Any update on this engine Ralph? I found this very helpful as I’m having the same issue with my 2010 Equinox as we speak. Thank you for taking the time to teach people-

8:04 “oop, shoulda unplugged that airflow.. my bad” 🤣😂

Hi Ralph, good video. I always tell people to listen to the engine during clear flood mode. I am also old school and still use a vacuum gauge in some cases, but also like to use my OBDII scanner. I also have an Equinox with the same engine. I have seen reports of imitation NGK plugs from China that may cause damage such as this. Were those the original plugs and or what brand were they if replaced before?

Good video 👍

Could have put oil in the cylinder to see if the compression went up. This would tell you whether its the head or cylinder. You seem too nervous about people not believing you figured out what was wrong with the engine. If you wrench cars and couldn't figure it out you probably shouldnt wrench cars. Point being I believe you figured out the problem without question.

my equinox 230.000km on clock and it start same problem today

If the injector was stuck open - there always would be fuel on the plug, correct?

Good video

Good

what did the customer end up doing with the vehicle?

Okay what if it's not starting up at all and I have codes P0300, C056D-00, U0100-71. I have replaced the high pressure fuel pump, so is what do I need to change??? Please help I'm stranded and wasting money and I need to get my truck fixed.
